![]() the 2 piece hollowtech cranks are sooo much stronger.Īlso, 500w does not seem like that much juice for climbing. used to break those all the time in the old school mtb days. I am also concerned about the square taper BB and cranks. I have noticed that there are aftermarket alloy rings and chainring spiders. Also the steel rings are huge and flimsy looking. I'd be worried about hitting it on logs and rocks. I am not really a fan of how low it mounts in front of the BB. The bafang mid drive does seem like the best climbing option. I'd prefer that the hub wasn't insanely heavy and that it didn't have tons of drag when not on the juice. I'd like to keep the bike as lightweight as possible, as well as off road capable. Good luck with whatever you choose to do.įor the MTB's, I really want it to climb that 1000ft elevation climb. Both of these motors were designed for 26" wheels and are laced into 16" wheels on the trailers. The little geared motor does fine, but it tops out under 15 MPH on the flat. They can both climb 15% grades, but the direct drive motor heats up. I have set up two friends with one wheel trailers using hub motors. If you use a small hub motor you have to be careful not to let it lug down on steep hills, which means you have to be able to help it enough to keep your speed up. On my recumbent trikes there is such a long chain that with just a standard derailleur I've had no chain issues. On my sister's bike I installed a Nexus 8 IGH with no chain guides or tensioners and she hasn't had any chain issues in almost 2 years. Light weight, efficient, bikes feel the same and can easily be pedaled without using the motor, good acceleration and top speed, and good hill climbing ability.ĭownside of the BBS02 includes price and, on a regular bike, possible chain issues. Last three builds were all 48V 500W BBS02s, one delta trike, one tadpole trike, and one 26" cruiser for my sister. I have become a big proponent of the BBS02. Īfter at least a dozen different builds with various hub motors, trailers, bikes, trikes, etc. I'd like this bike to be pedal elec, no throttle. I'd like to have battery/controller all in rack bag, discretely hidden. The bike is 26lb touring bike, with triple and canti brakes. ![]() Novara touring bike with Qute Q100 geared hub, lightweight, minimalistic build. I'd plan to fill in the "tank" with styrofoam and ducktape.ģ. I would want lipo batteries, in the cavity of the front triangle of the frame, in front of the shock, as well as to the side of the down tube/top tube, starting where the shock is. This bike would be less about pedalling, more throttle. ideally like something where I pair 4 batteries together relatively simply. I don't wan't to get too crazt with battery building. I'd like to keep the batterys in the front triangle some in cavity between tt and dt in front of the shock, and some to the side of dt/tt. I'd want to do the same climb as before, but more power, less concerned about light weight. Buddy is asking $300, think I can get it cheaper. I am torn between cheapy ebay 48v 1000w, golden leaf 48v x 1500w and bafang middrive, with 48v x 20ah triangle li ion or lunacycle.Ģ. I understand lipo is lighter, higer performance, but more finicky, and to some degree think that a li-ion set up makes more sense for first build. I am moderated by desire to keep first project affordable, easy to build and maintain battery. Battery, hub, controller, I'd all like to keep as small and light as possible. Ideally, I'd like the battery and controller all contained in the front triangle of the bike. I would like to keep the kit as light as possible, and the bike as efficient as possible. There's another side of me that thinks a bafang middrive BBS-02 is the way to go. There is one side of me that says just keep you're first build easy and get a dillenger kit. What hub/battery combo do you think would tackle this once? twice? I am open to buying hub, controller, battery separate. Would an ebay 48v 1000w wheel kit, $200 and 48v 15ah li-ion triangle shaped battery do this climb? Should I get a leaf bike 48v 1500w?, $340 This bike has a ton of room in the front triangle. I am going to pedal, I just want it to go faster. I currently pedal this climb in a 30X36 gear. I would like to make it be able to cruise 20-25mph or so, along lake road for 3 miles, then climb this 2.7 miles, 932 elevation gain, 6% average grade, though it gets to 15% in spots. I have 3 design ideas, and would like some feedback on which might be best first project to tackle.ġ.
