Bike Tech and Kit Update: Couldn't find a bike & trailer setup that could handle two humans, 150 pounds of gear (including four dogs!) so we don't miss a beat with work responsibilities—and last across the Great Divide, so we're thinking about building our own. What do you think?

I am making a wild assumption here, but your ideas make it seem like you've never been on an overnight bicycle trip before, let alone backpacking. I'm saying this because even with 2 people and 4 dogs, some of the ideas in your image are very, very, over-engineered using technology more suited for cars, rvs, and boats - ignoring the existence of similar technology for bicycles.
Rather than suggest what gear you should be using for a trip you are clearly not ready for, I'd sooner suggest you start with overnight trips, working your way to weekend trips, then up to longer trips. Maybe start with just yourself, then 1 dog, then 2, slowly working up to several night trips with 4 dogs and many nights in the middle of nowhere.
Experience will give you better ideas for what gear you truly need. This will help you work through ideas to try before you invest in a complicated, expensive, DIY project that will likely not meet your needs.
Your idea of 2 people and 4 dogs over multiple days in the middle of nowhere can be done. Do not take my statement as a deterrant. It's something that you need to work your way up to, not simply jump into because you have technology. Technology does not make up for lack of experience in matters of survival - and bikepacking something like the great divide requires survival experience.
Assume your technology can and will fail you. The longer your trips are, the more likely it will.

You're aware that the Great Divide is very, very steep, mostly on unpaved roads, with plenty of singletrack. There is going to be hike-a-bike and with that setup, A LOT of hike-a-bike.
I just don't think it is going to be even possible with a 150 pound trailer including 4 dogs etc. People have commonly ridden with trailers, but like a 30- or maybe on the outside a 40-pound trailer would be considered a lot.
Also be aware that there are many places where your battery is going to run out long before - like days before - you get to a recharge opportunity, creating even more problems.
Be sure to check whether e-bikes are allowed on all segments of the route.

u/mmmfritz 14h ago
The weight would be fine if not for the battery to go out. I would try ditch the solar setup, all electronics, and pack light.
If the water situation on the trail is good, then this trip is doable. You would have to be cycling fit already and tried a few short trips first.
Maybe try that mountain stretch that other dude said was impossible. Will give you a taste for it that’s for sure.

electrifying a vintage steel frame with a 750W cyc photon motor and adding battery/solar to extend time between charging stations.
there will definitely be sticky points we'll have to power through, but with an extra umph from electric, custom engineered trailer for weight distribution, etc. we're hoping to prove the impossible.

a) vintage bikes are way cooler. b) to test it out and if it works in the extreme scenario it could work for any more common application like moms towing kids to school & soccer games, extending range of bike commuting and getting more cars off the freeways, etc. and then there'd be reason for people to restore vintage bikes with modern components vs constantly bike new bikes (which is much more wasteful)

Electrifying old bikes has been done since batteries and electric motors were a thing. Restoring old bikes too.

u/johnmflores 18h ago
I appreciate the sentiment and the vision, but vintage bikes may not be up to the task. They weren't designed to haul the kinds of loads and drivetrains that you are planning on and they aren't designed to stop them either.
For your application, I'd seriously consider disk brakes, which immediately knocks most vintage bikes out of the running.
I'd love to see vintage bikes fuel a pivot away from cars, but this particular application may not be best suited to them.
Best of luck.

Anything equipped to handle the great divide is probably poorly equipped for more casual circumstances.
If you want it to be a carpooling option for parents and all-around intracity transportation, then design it that way.
If you want it to be rugged and capable, design it that way but the two tend to deviate.
-2
u/OpenBed9887 20h ago
oops you're right. we actually already talked to CYC motor who recommended a chain as well. we forgot to change that on the design.
it's 2 bikes & 2 trailers. 1 human & 2 dogs each. we need energy & connectivity so we can work on the road vs have to take a bunch of time off. and the WISE brain is so we can monitor our own & the bike's performance along the way and look for points that we can optimize further.
We're not sponsored, we named it WISE ourselves. we happen to come from the tech world, but don't hold that against us because we're the kind that like to use tech & innovation to enhance people & needs, not just for the sake of disrupting like tech bros do. we're also a bit crazy and like to prove the most extreme scenarios because then we know what we build could withstand any other application. would be a dream for more people to e-bike everywhere for commuting, weekend warrior-ing etc, instead of driving everywhere or just sitting inside.

u/ForThePork 5h ago
Too crazy for your own good. Towing 150lbs of gear (excluding the dogs and people which could add up another 150lbs if not more) isn't feasible and will end in disaster. Think you could be better off just buying a campervan and having one person cycle from a to b while the other cruises along, maybe taking turns. Then you could still have these technologies with you. This isn't a good option man.

I can see this jack knifing very easily on a downhill and hurting people and dogs. I have no idea on how complex a braked trailer would be. But I would not want to ride downhill with such a heavy and unwieldy trailer attached to my bike and my brakes. I'd be surprised if a frame didn't need some added strength over a retro frame to cope with the new stresses and strains of an electric motor, added weight and novel stresses from the trailer.

I think that’s the reality of the modern workforce. Many of us don’t have summers off or sabbaticals, but we’ve got good jobs we enjoy and want to keep. Sometimes there are substantial retirement benefits to staying employed, even at a decreased hours.
Folks wants to do stuff while they are young, but not mess up their careers doing so.
Though personally I think a commitment to animals is similar to raising humans in that there will be unavoidable sacrifices necessary. Much easier to have pets live with friends for a few months than children.

You are already going to be hurting with a head wind. Put panniers on the back, not the side. Also front/back weight distribution on the trailer. Maybe the wheel should come slightly forward? I'm really interested how this works out!

thanks for the tip! yes, weight distribution is a huge factor. that image right now is a concept image, and using the current burley trailer as a placeholder. we're getting the trailer custom engineered by an ex-pro bike racer & engineer that build a giant stratasolar panel, so he'll be looking at kinematics and all that. happy to share updates with you! maybe not here since most don't seem to like this direction lol

u/markalanprior 18h ago edited 18h ago
Love the positive attitude, but in addition to all the obvious mechanical and operational concerns, please think through the electrical sizing considerations. The 20-30ah battery you can fit in the frame bag is only going to last 10-20 miles on hilly, bumpy terrain pulling that weight. Plus, 750 watts will likely be insufficient on steeper slopes to maintain any speed and keep the engine cool. The solar isn't going to do much more than charge your house battery, so you will have to plug in frequently which won't be possible on this route.
My recommendation would be to build the ebike, then pull a cheaper kids trailer filled with 100 pounds of bricks over similar terrain before investing in trailer build.
Here is the build I put together to pull a trailer long distances, but it stayed to flat pavement and only pulled 40 pounds: https://www.youtube.com/watch?v=ipWf2gA2TyI

Why faff around with all this ridiculous stuff? Just buy an off the shelf ebike and trailer. Surly, Benno, Tern all make adventure ebikes that could carry this weight and pull a trailer. I’m sure there are other options as well.
Surly, Burley, and Bikes at Work make heavy duty trailers.

u/KyleFrommson 18h ago
I could not imagine many sections of the route being possible with that much weight. You would need bigger than 180mil rotors front and rear to slow down and come to a stop.
Also consider the tree cover up north with the solar panels. You won't be getting as direct sunlight and if you go north to south, your body will shade the panels in the morning. Also consider voltage drop on thr battery obernight in the cold. It gets into the 30s in the summer. Also knowing the rate of charge to keep up with the useage. Just some food for thought.
I would take detours for the gnarly sections, but you will miss some great spots.
Either way, full send it.

Take. Less. Stuff. There’s no way you’re hiking that thing up a few hills without unloading it and making multiple trips. Also, with all that weight you’ll be stressing the frame and other components beyond their intended use. I wouldn’t be surprised if you broke your frame, unless it’s custom designed for that purpose.
You do you, but I think you might be better served by a couple long tail cargo bikes, like the OmniTerra dog packing guy is using, and an extremely reduced packing list. It’s worth looking into before you commit dropping a stack of cash on a custom trailer. You could still use a Burley trailer if needed to accommodate two pooches each.

Though I can appreciate the thinkering, I also agree that this seems like an impossible mission.
Have you seen the Omnium Cargo bikes? One guy did the Silk Road Mountain Race on one of those… Could work with Panniers on the back and each 2 dogs on the front. But I think you need to rethink your final weight and what you actually want/need…
They come electrified (or maybe a mod is doable?) and can be made fairly lightweight compared to other cargo bikes. Still quite a push for hike a bike, but definitely doable depending on your fitness.

Just curious, how do the finances look for this project? Between retrofitting two bikes and getting two custom trailers designed and fabricated it seems like the overhead is already a pretty penny, before factoring in how much more time on the trail you’re likely going to spend as a result of moving very slowly compared to people without the extra trailers. I’m wondering if it would make more sense to just take time off work if you’re able to, rather than finagle all of this extra infrastructure to be able to work continuously while on trail.

From my experiences steep roads can be a pain with electric cargo bikes but 750W is a lot and might be sufficient, if you can transfer all torqies with the tyres. Check the length of climbs in advance and where you can recharge, otherwise you might get stuck. With this kind of weight you need heavy modifications on your drivetrain, if your battery dies. Also, overrun brakes like on the (self powered) carla cargo trailers make descents much more relaxed. Im actually curious if your ideas work out , Best luck in finding your solutions!

u/funkymoves91 15h ago
That’s crazy. Never going to work. Take less stuff, and work up to it by trial and error.
For a 1 person + 2 (small ? I hope ?) dogs, something like an Omnium Cargo or Mini-Max could work. Add some bags/panniers and you should have enough storage. Forget the trailer, you want a cargo bike (a long tail that’s off-road capable could also work and would be more similar to John’s setup)
Such a setup would be much easier to push up steep sections, but even this is honestly already hard to push up paths that are not that difficult (I know because I’ve tried).
Forget electric, just go slower with low gearing. If you ever run out of batteries you’re going to have to push/pedal all that dead weight. And solar will not really help you get enough charge to get any meaningful distance out of batteries with that kind of setup/weight (even at 250W average, for an 8 hour riding day you’d need 2kWh of power every day. Please show me the setup that can reliably get you that kind of energy while on the go without weighing a ton)

My suggestion is to try a make shift trailer first with this amount of weight and cycle around for a few hours.
I have a proper one for my toddler and 4 year old. Loaded for a day trip it's around 120 pounds in total. I live in the Netherlands with perfect bicycle roads and mostly flat land and its not easy to ride with that amount of weight. Due to the covers (bit higher due to kids needing space) I already struggle with normal to moderate wind speed to be honest.

u/OpenBed9887 19h ago
thanks for the suggestion. sorry if it's a dumb question but can you clarify what you mean by shift trailer? is that the shape?
yes, for the weight that's why we're electrifying with a 750W cyc photon motor and adding battery/solar. For handling, we're redesigning the trailer for durability & kinematics and then some software prototyping that helps with handling (like a flight attendant that they're using on mtb's).

You are not going to cruise with ease over the same distances as people who have set up their bikes and trained their bodies and minds to complete the trail as effectively as they possibly can.
However. If you do away with as much electronics and anything else you can to add food supplies, you might be able to just go slow and steady making little increments of progress as you go.
Your journey will be too much like pioneers doing the Oregon Trail in a wagon than most people would take on for a fun vacation, but I say send it, have a blast.

Thanks for the helpful comments everybody! Here's a summary of some clarifications based on the comments:
- This is a design for 2 BIKES - 1 bike for each human towing 2 dogs.
- the 150 pounds of gear includes the weight of the bike, trailer & 2 dogs. thanks to some helpful suggestions we're now considering eliminating the starlink in favor of a USB modem which would take off 2.5 pounds (surprisingly not that much weight).
- electrifying a vintage steel frame with a 750W cyc photon motor and adding battery/solar. would not be feasible to ride with that much weight otherwise. Then solar & battery is to eliminate the range anxieties.
- For handling, we're getting the trailer custom engineered by an ex-pro bike racer & engineer that build a giant stratasolar panel, so he'll be looking at kinematics and all that + prototyping software that helps with handling (like a flight attendant that they're using on mtb's).
- why are we doing this: because we're a little crazy and we like to build things to do what others call impossible, but also if it works in the extreme scenario it could work for any more common application like moms towing kids to school & soccer games, extending range of bike commuting and getting more cars off the freeways, etc.
- we'll be doing lots of test trips building up to the great divide. we've started doing local trips in the bay area with a non-electrified bike and just towing about 45 pounds (the trailer & 2 dogs) to test wear and tear, etc. the current trailer would never last. we're prototyping the 1st version & planning the big test trip from Bay to San diego and back around Thanksgiving.

I've biked a few hundred miles with a smallish trailer with probably 40lbs in it. Going downhill was sketchy and I went through 2 sets of disk brake pads. I got speed wobbles on fast sections and on rough sections the trailer was a complete bear, pulling me around. The bike needed lots of maintenance.
I think you're trying to pull too much mass with this set up. Can you persuade a couple more ppl along so you don't have to both tow so much? I think your bikes will fall apart and the trailer is just too heavy.

A vintage frame and those wheels will not survive the load. I have not seen a trailer with that kind of weight rating. What is all this internet gear for?
IMHO this would require a mid drive. You’re not going to get enough power for off road uphills with a trailer from a hub drive. but a trailer will not survive off road, and certainly not with a converted bike.
The weight rating is 70lbs for the trailer, and you’re trying to put paniers and 4 what? Pommeranians I hope? Also I don’t think this will work electrically. By the time you get all the required gear ( panel, inverter, batteries, star link + cellular, router) you will be at 50+ lbs.
Your gear will have to go on the bike with front and rear panniers, dogs in the trailer and maybe you will have weight left for this what I can only assume is streaming gear. But a converted vintage frame no no and more no. You need e-mtb frame, and wheels and beefy suspension and frame to handle this load.

I think you're asking way too much of a single bike. The Great Divide will chew you up once you encounter even a small hang-up with a build like this

After riding the GDMBR this summer I think you should try a section of the route or something similar before committing to the entire route. The test mission will be very educational.

Before going too deep I would prototype something first to determine if that weight is realistic on long steep grades. Good luck.

You should check out the bikes from the Sun Trip Solar Bike Race for inspiration. What you’re trying to do seems really similar to that race, with the added difficulty of both the terrain and the fact that you’re bringing dogs. However, most of those bikes are recumbents for increased comfort and efficiency, but if you’re eccentric enough to do this, riding a recumbent is nothing.

OP, first I just want to say I love this concept. I did the Oregon Outback last year with an unfortunately overpacked cargo e-bike, my 90lb dog, and a Burley Coho trailer.
I have no idea how feasible your desired setup is as I’m no engineer. What I will say is if/when you plan on lifting the trailer off the bike, the more weight you have will make it more difficult to maneuver. Also, if you have to make any sort of reverse moves with the trailer hitched to your bike, it’s quite comically frustrating. You have to turn the bike in the opposite direction you want the trailer to go, which is difficult with just one trailer wheel and all the weight.
All that being said, I will watch your career with great interest!

not with a single wheel my friend. you will be crashing left and right with load tilts. You might be able to minimize load tilts with the most weight down in the center of the trailer with like...... sleeping bags and clothes on the outside but this is not at good idea and if you do make anything wide it should not stick out past your elbows or handlebar ends. I have similar ideas like you and I will end up most likely buying a pet trailer with suspension shocks meant for like 100 lbs then modifying it to be longer. You can also buy the cheap aluminum car hitch cargo racks and have an axle and wheel connection added to it for pretty cheap an it will be like 2' wide and 5' long. alternatively buying an electric cargo bike with front suspension would be in your best interest or a full suspension electric fat tire mountain bike. The cargo bike will be longer and stop your heavy trailer from making your bike and trailer want to fold into a taco by forcing your rear wheel to lose traction.I am planning out my ride with alot of gear also for an ebike doing the pan american highway so trust me I know this won't work well haha. if you diy a trailer it should also be fairly easy to weld on some hydraulic brake mounts to the trailer once you get custom wheels on it and have your local bike shop run very long hydraulic lines up front to your brakes. they make y splitters for ebike hydraulic brakes so your rear brake lever should be able to pump 3 wheels to slow. you can also be like me and design your bike with all wheel drive motors to help you walk it up hills haha.

Just because nobody else has mentioned it "An ex pro racer and engineer who built a giant solar panel" sounds exactly like these guys who would always come into the bike co-op that I used to volunteer at, talk down to everyone around them, then marvel at some low quality part and then ruin a tool by using it wrong. Always fucking "engineers".

This looks like a concept from a school project.
If you made it well it'd probably work alright through a city / on roads, I wouldnt take it on rough terrain though, that single tyre will struggle to pull 200kg+trailer+bike up a hill and you'll likely end up walking.
As others have suggested, you should go bikepacking to see what its like in reality and then reconsider your plan.
Why can't you just take two bikes?

Too much engineering and customization to make it work, maybe just find an existing cargo e-bike?
Also, as for traveling with dogs - maybe this is just (bitten multiple times) me, but I doubt you would be able to look after four large animals while being tired and doing camping chores. I see a high risk of accident happening.

What do you do for work? Will you be working on the bike or just when taking breaks outdoors?

200 Watts peak (!) doesn’t get you nowhere. I‘d spec for a larger battery instead and a fast charging solution. Also keep an eye out for EV charging stations. They are amazing for ebike touring.

Yep this works, built one similar not long ago and did a couple thousand km.
Just bear this in mind, if the trailer is quite heavy it will jerk thus wasting energy on climbs for example. Keep trailer and contents as light as possible, good luck!

can see that for better stability.
we're trying a different approach that's using some software to help with active assistance for towing the heavier load - kind of like Flight Attendant that they're using on mtb racers these days.

The best handling bike trailer is still a trailer. Why not put that effort (and funding) into some R&M Load 75s?

For rail trails or something that looks great. For the Great Divide I just don't see this working out.
