I own a very nice Yuba V4, and a just fine Trek Commuter Bike. I like to bike to work; it's roughly 5 miles each way, with some SIGNIFICANT grades between; I have seen many spandexed weekend riders walking up one of the hills on the way home to my house.
I can barely get the Yuba in and out of town, and with a kid on the back it's a major difficulty = I don't do it.
So, my original plan was a stokemonkey, then they were discontinued. Then, my plan was convert my Trek, throw a seat on the back for one kid, and later convert the Yuba.
I commenced researching e-bike conversions, ended up here reviewing circuit board diagrams and freaked out.
All I want is to get in and out of town on my Yuba with up to two kids on back! Is that so wrong?
I'm 6'0 and 225 lbs. Speed is not a major requirement, but hill climbing is.
So, here's my question:
1) Is it so cheap to convert the Trek that I might as well do it as a warmup before I do the Yuba? I'd eventually like both done so that my wife and I can take everybody around town between us.
2) Pedelec systems... What's up with these? I tried one and liked it. I WANT to pedal. I hated the StokeMonkey's forced pedaling. I also don't like the idea of just using a thumb twist whenever I go somewhere. I want to pedal, I just want some help. Are these systems significantly more complicated to get working?
3) What sort of budget should I expect for the Yuba? I noticed Yuba sells a kit, but it looks like just a front motor. It's really hard for me to imagine a front wheel pulling what could easily be 400 lbs up some of the hills near my house.
4) How technical are these builds? I must admit, I'm overwhelmed at this point.
Thanks for the advice.
there are three ways to convert Yuba cargo bike:
1.) Yuba USA is now selling eMundo, contact them and see what the can offer you:http://yubaride.com/electric-cargo-bicycle
2.) Urban Commuter sell a mid drive system, very similar to stokemonkey, except this is custom build for Yuba, work excellent, check the store and youtube link belowhttp://urbancommuterstore.com/http://www.youtube.com/watch?v=R5ZdbAGKJ90
3.) The Yuba rear drop are differ from standard bike, in order to use rear motor, you need to have custom make Yuba torque plate, once you have the torque plate, you can install any rear motor conversion, in this example, Kiwi, one of our member had made it available to anyone, check out the link, and Kiwi build threadviewtopic.php?f=31&t=31881&p=464241&hilit=kiwi+yuba+torque+plate#p464241viewtopic.php?f=6&t=14375
I personally use xtracycle with electric assist, in comparison to Yuba, xtracycle are much lighter weight, most of my cargo in around 200lbs, I am fine with it. But if I need to carry 350lbs+ cargo, then a Yuba is the workhorse for it.
In regarding the 3 option that I suggested
option1 is basically a eZee front wheel kit, there are a few vendors that sell them. But I think eMundo may have proper mounting for the Yuba, you should find more information directly from yubaride.com
Front wheel drive on cargo bike is not a bad idea, when you put 400lbs weight at the back, and going up the hill, you could start lifting you r front wheel, which make it unbalance. By have the front wheel, it put the weight down at the front.
option2, is an improved design from stokemonkey, but design for Yuba. A mid drive system will give you more low speed torque, for climbing hill, it is a wonderful setup but a bit more noise.
option3, it open a lot more option for you, with the kiwi torque plate, you can use almost any rear motor kit for the job. But most people will have choose the biggest motor as possible for carry heavy load.
I hope this help you out.
