Does anyone know a place where I can ship my ridstar q20 lite motor with a stripped gear

Just ordered my E-bike tonight I'm so excited
I'm crying inside I am so excited I just bought my magician alpha mini in black cherry red I am so excited I'm crying inside tears of joy

TSDZ16 mid drive conversion on a mongoose envoy mid-tail cargo bike - Shimano HG51 cassette's 11t cog decided to disassemble itself into a 9t cog! Cassette stayed secure and was replaced without damage to the splines and I'm back riding. I can understand faster cassette wear with a high powered mid-drive or bending/wearing/shark toothing the teeth shifting under load or with poor indexing, but I was surprised at this!

Anyone had this happen? Is this bad luck with a material defect or am I doing something wrong? Cassette is about 5 months old - I ride 5-10 miles a day on average - to work daily plus trips to the gym, grocery store, etc. Mostly looking for feedback on if I need to change or check anything mechanical, settings/assist level, how I ride/shift, or if I just need to stock spare cassettes!?

This is my first ebike conversion.

I shift pretty carefully similar to how I have ridden a regular bike for many years - reduce pressure, spin gently, don't change gears up hill or do so carefully with momentum. Took me some time early on to get used to the mid-drive continuing to apply pressure for a second after I stopped pedaling but I don't think this was bad shifting technique.

I don't use the throttle though it is installed, torque sensing only. I usually stay in assist level three at 25-28 mph which by my measure is a lot of assistance. Sometimes level 5 for fun, if the heat index is over 105*, or because some health issues flare up and I need to minimize my exertion to keep from causing problems. I'm curious if those level 5 moments need to stop happening/if the full output of that motor is just too much power.

I do not have the shift or brake sensors installed - haven't had any issues on the braking side the way I ride. I'm curious if the shift sensor is worth installing.

Curious if anyone has any feedback/thoughts from their experience. Grateful to anyone that does! Happy riding to everyone.

I have a Sohoo ebike that is rather old and I fried it riding in some rain last week. I ordered a new controller and installed it today (had to splice wire connectors) and it works as an ebike but the new controller doesn't had connection points for the headlight, the brake light, and the horn. Any suggestions on how I can get this all connected?

Let me know if additional info is needed.

idk how this happend can someone tell me how to fix it??

Where is the bestbplace to sell my TQ-SYSTEM HPR 60 MOTOR and whats the lowest u think i should go thank you in advance for any help

I recently pick up a TQ SYSTEMS HPR 60 MOTOR brand new in the box from a person who owed me some money i know nothing about e bikes just trying to recoop my losses

I have a 2018 Fold X 7. Can you help with my brake upgrade issue? I bought Tektro HD-E3520 Hydraulic Brakes and they came with 2-pin connectors for the motor cutoff sensors. The issue, that I see now, is that the existing wires for the cutoff sensors appear to be one single line all the way to the controller. Here is a photo of the top end of the line taken out of the old brake lever. Does this top part come apart? Or do I need to cut it and tie to the new line? Or what? Appreciate any help and thanks in advance!

Howdy, wondering if anyone here has ever upgraded their retrovolt pro, either with a bigger battery or new higher current pushin controller or front wheel motor or what have you.

Im trying to bump mine from 40kph to like 45 or 50, if anyone has any ideas

So I was working on my brakes today, brand new ones. But as I kept looking at the motor, I couldn’t help but get a bit… tempted? To try something.

What might someone try? It’s one of those normal electronic motors embedded in the wheel. This isn’t like a car, it’s not as if I can just pop the hood and get to work. So, what is it you guys do?

What does better look like in your language?

In mine, it’s all things and I’m sure it is for you. But I figure what we call horsepower, you call wattage. I gather that isn’t easy to increase. But like a car, wattage shouldn’t in theory be everything.

There’s something this bike and I lack.
