That's close to the initial idea i had with the mentioned motor (Aliexpress).

The problem with the motor you linked is that its gear reduced RPM is about 700, and it will be difficult to get the wheel speed you're looking for with a single stage of external reduction.

Its B67 and nothing looks out of place. Ad says $225 or $250 new, asking half. I am 280lbs Screenshot_20220517-021351.png That's a good choice of model for someone your size. I would buy new if I were in the market for a leather saddle. That said, my ex-wife's favorite saddle is the Brooks Flyer S ...

I didnt know hub motors were bad at uneven / bumpy roads, crap. Does it break easy? We kinda live close to a forest and not say 10minutes car drive from nearest "village" so pretty much gravel road with some bumps and our forest my son drives in when tracks are closed. Gear reduced hub mo...

Looks good but waiting for the live test. It can still take a seven-speed free will if you widen ithe frame ? I remember it was heavy You can add some spacing, but it will adversely affect dish and spoke tension. It weighs 19.2 pounds on my untrustworthy little digital luggage scale, with all the a...

Oh, and for the OP: Have you seen this? https://www.amazon.com/QSMOTOR-bicycle-Brushelss-including-freewheel/dp/B07DC27M94 I got one. Haven't fired it up yet, but it seems pretty boss from what I can tell. Only supports 1- to 4-speed freewheels on its original spacing, so suitable either for a fatbi...

I'm looking at a 5303 but has a 48v controller with 4110 fets so sounds like a 72 v controller ?

5303 is a fast wind; it works much better with a lower voltage but lots of phase amps.

Looks to me like there's a gap between the frame and the wheel that could be used to fit a 48t (or whatever appropriate size) sprocket. Instead of a spacer, there could be a keyed carrier for a chainring. Yes, but then you would have to move the chainrings and chain to the outside of the frame. May...

There are plenty of options for Hailong, Polly, and probably other frame mounted hard case batteries that have a speed controller in the base rail. Topbikekit has a bunch of them. Don't fool yourself that they're waterproof. For weather resistance, the best thing is to let moisture escape as quickly...

The model is 1500W, freewheel rear version is probably best for what you're doing (because you can mount a sprocket on either the disc brake side or the freewheel side). But if you look at the picture, the freewheel is mounted on the axle inside the frame about 3 or 4 inches from the wheel. The whe...

About the suggested motor from Leaf, do you have a link to a specific model. I searched there website and there is quite a large amount of different models. The model is 1500W, freewheel rear version is probably best for what you're doing (because you can mount a sprocket on either the disc brake s...

Thx. I did try to amount the BBS02 on my Cannondale hybrid road bike, but the BB "socket" was slightly too small to accept the 33.5mm spindle of the motor. I think these Cannondale specs may explain it. https://wheelsmfg.com/bb30a-tech-info Hope I have better luck with the Kuwahara. You l...

If you only have two motors, well... you're going to need at least two wheels. I don't see the need to conjoin these twins.

Its easier and cheaper to limit power then it is to make more, higher power. I was going to say Leaf 1500w hub motor if you want two motors, or a single qs 3000w hub motor If all he wants is sub-5 mph, power isn't really the issue. It's gearing. Leaf motor is a great choice because he can get 11t w...

If you're keeping the stinking gas engine, what's the point of converting it? You just want a heavier car that wasn't engineered to be that heavy?

Good luck with your auction.

In the future I strongly suggest not wasting your effort converting bikes that were garbage on day one and will only ever be garbage.

You have to take out the bottom bracket first. Then the BBSHD will mount on the threaded shell.

No, there is no list. Given the number of bikes available, that's like asking "is there a list of people who look good in these pants?" If your bike has a threaded bottom bracket shell and a straight down tube that slopes upward towards the fork, then it's overwhelmingly likely a BBS02 or ...

Chalo, Can you at some point in the future post a pic with the two different types of "front washers"? I'm guessing that it's a bent tab vs an elongated tab, but I'd like to see the differences. Right kind: IMG_20220505_084412126.jpg Wrong kind: IMG_20220505_084544820.jpg Both kinds: IMG_...

Not sure if you guys are aware but none of the big brand torque sensing bikes like trek rail, Levo, etc have cut off brakes. If you choose to do so then that’s totally up to you. If you have a throttle then it’s a must. Why is it "a must" for a 1 HP vehicle when no vehicle with 100+ HP ha...

When I get a non-running Bionx bike at the community bike shop where I work, I de-electrify it. There's no time-efficient way to get these overly proprietary bikes running again. They offer a cautionary tale against buying a system that won't let you keep it running without Mama's consent. Sometimes...

You don’t need brake sensors with a torque assist bike What's your rationale for that statement? If you don't want to strip your blue nylon gear regularly (or be really really careful about braking under power) then you absolutely do need brake sensors with the tsdz2. I agree. My bike feels much sa...

20mph? I barely get 10 miles per hour.

You have some problem with your system. What are you using for a battery?

Two AliExpress sellers in a row have offered "front" washers, used a picture of the correct item in their listing, and then sent me washers that don't work with fork tips. Which AliExpress sellers did you try? I just ordered 2 sets from here https://www.aliexpress.com/item/100500322366293...

Promise us you'll tell us if the fork breaks off (if you can). Would be more productive to explain where and why you believe the fork should break and how you suggest to fix it. :wink: You did see that the forks are held onto the steer tube with glue and pieces of plastic, yes? Here's one of the wa...

Hopefully this is not the end of the jump wheels. It is from BCH. I just got this e-mail: The wheels were a one time purchase, at this time we don't have any plans to bring more in. It was a windfall that came along when Uber sold its Jump bike business to Lime, but that sale didn't include the bik...
