    Rear Hub Motor - Build or Buy

    Salvaged cells, yes BMS, and yes to shark case <3. I can do it for 150 to 200 and be pleased when I put it together. I'm not an ebike purist, if I do the math right then 5/piece 20C brand new fresh out of the child's hands cells won't offer me any practical benefit over affordable, salvaged...

    Rear Hub Motor - Build or Buy

    This is the bike I’m planning on using for the conversion, I’m not worried about laying everything out like I said, mostly just picking a motor. Here’s my current very real electric bike 100% solar powered it just happpens to sound like a 2 stroke. Mostly flat here, idk like 150lbs maybe...

    Rear Hub Motor - Build or Buy

    Schwinn Santis. Surprisingly decent sans low travel fork. As for the battery, I was thinking I’d just tape a bunch of AA’s together. But really, that’s actually the area I’m most confident in and least worried about. I have one of those cheapie portable spot welding power banks that works just...

    Rear Hub Motor - Build or Buy

    Yeah, I know about torque arms and such, I’ve got some experience with ebikes, just haven’t purchased anything in quite a while. I’m still likely to build my own battery. I’ve built them in the past and am confident in my ability to pick out some good cells. Will see how things go, I’ve sent...

    Rear Hub Motor - Build or Buy

    Solid points all around. Sorry for my misunderstanding, just wanted to clarify this bike is a bit above a BSO so I'm not terribly worried about durability, but now it seems I'm back to the hub motor as the best option. I may go this route, if I can find a decent 48v 1000w kit for like 200 bucks...

    Rear Hub Motor - Build or Buy

    Unsure if that last paragraph is a jab or not. I’m quite happy with my hydraulic disc 29 inch hard tail. Either way, thanks again to all the feedback everybody^^. I’m kind of fluctuating based on my research and yeah, it seems like finding a 29 or even 27.5 hub motor kit would be cheaper...

    Rear Hub Motor - Build or Buy

    Right, that’s pretty convincing to be honest. At first I was skeptical about the shifting, but that sounds actually like a positive. Can’t seem to find a bbs02 for sub 400 which kind of brings me back to the hub motor + wheel build option for up to like 150 less. Will do some more research, if...

    Rear Hub Motor - Build or Buy

    Thanks for the all the help so far. After doing some more research I’m reconsidering whether or not it’s more economical or practical to go mid drive. I’ve only used direct drive, but thinking about where I’ll be riding, city and trails, low end torque is more important in reality. Plus I...

    Rear Hub Motor - Build or Buy

    Hello, I've decided to say f*ck it on the frame and just convert my current hardtail into an ebike and force myself to love it. With that being said, it's a 29er with surprisingly nice WTB rims for a walmart schwinn. I've used a hub motor before on a small little eBMX project (but I used a...

    What frame style is this?

    Hello, I’m looking to build another ebike, and for reasons I can’t quite explain I need a very specific frame style. Something like the cannondale super v frame, I’m not sure what this exact frame style is called, but I’ve seen it on some cheap Walmart bikes. If anyone knows where to look...

    BionX battery mounting rail?

    Well at this point I’ve already decided I’m gonna rewire a bms and put the battery back in commission, but I may sell it later. Honestly I’m very close to just finding a cloth sleeve for it clamping it to my bike. 60 cells actually don’t take a lot of room .

    BionX battery mounting rail?

    One of my dads Facebook friends just gave me an old BionX “triangle” style battery. It’s just a 36v 9ah Li-Mn rectangle battery inside a weird looking traingle hard case (kinda looks like a shark fin). It has a mounting system that requires a rail that it slides into, and I believe you screw the...
