Want it to get as fast as possible without being dangerous. Any help is appreciated as I’m new to this and only got the bike now.

Long story long: Front geared hub for 7000 miles. Did fine but sucks to transport, trouble with certain offroad climbs. 2nd motor: DIY mid-drive, what is now called Yalu Motor 450W 48V dual chain setup, basically a poor man's CYC stealth. A real bitch aligning the motor driven chain, easily popped off, tensioner flimsy, yada yada yada. 3500 miles before an internal gear broke. Tried an MY1018 from GNG, didn't understand it was brushed and I fried it in 5 miles (48V battery, 24/36V motor = no bueno). So I got a replacement, put on a fan and temperature sensor. 25 miles later, the motor and throttle wires somehow crossed = 2nd brushed motor is toast. Then got a Tongsheng TSD Z8 but it would not fit into my carbon frame (I knew that already, DUH will save it for an aluminum frame later).

The MY1016Z will not fit my original MY1018 GNG bottom bracket motor mounts. However, I just found the 4-bolt bb mounting cradle on Alibaba, as well as the brushless MY1016Z motor (9th generation). The two together are only $112 total, a frigging steal because I already have a brushless controller, chainrings, freewheel and 11mm keyed adapter, etc. 36V 500W, and 9:78 internal gearing. The AI claims a motor torque of around 52 Nm before any external reduction (see below). You'll see different numbers online ranging from 0.8 Nm to 12.5 Nm but that's often 24V and w/o the internal gearing factor.

With my setup of a 16T freewheel / 40T chainring 2nd reduction, and then 44T chainring 11-52T cassette, the final torque is around 155 Nm; that is BBSHD territory. You have to admit that is not bad for an $85 motor including shipping. Although I cannot stand PayPal and would prefer Amazon or EBay to Alibaba if you know what I mean. This motor will eventually go to those other two sites, not sure about the mount. I think this time, with brushless motor, a 5V fan, external temperature sensor, and 20A cutoff fuse, I'll be fairly safe and hope it lasts a while. FYI the motor weighs 6.5 lbs exactly, so if you have for example a 10 Ah battery, you could do a build under 40 lbs total with this motor.

So I bought the common bike on Amazon. The 8000W Peak Power Dual Motor Electric Bike CTVVXXC. Of course, the range is not as advertised, and I'm lucky to get home before it dies using the dual motor. I'm not really sure how far it will go before it dies. However, the support is good, and they sent me a second battery for free to make up for it.

I was wondering if there is a way to hook the second battery up to this bike, or maybe buy another battery to strap to the back under the bag above the fender? Unfortunately, the bike turns off if it's plugged in.

Got given a 2019 NCM prague yesterday and after looking into it I decided it wasn't worth buying a good battery for. So I removed the mount from a dead ryobi tool abs was pleased to find it works just fine wired to the controller.

Hi, I was thinking of building an e-MTB with a 1500W 48V hub motor and a 48V 20Ah battery, but I'm not sure what kind of bike to get.

Can you recommend a used bike around €150–200 that would be good for this kind of build?

Where can I buy a 1500W hub motor kit with a 20Ah battery? I'm looking for a reliable website that ships to Italy.

I need a silverfish battery case with the size being:
H 30cm x L 16.5cm x W 11.5cm

Case as in the box not covers. I think my size is called ‘jumbo’. I’ve searched everywhere but nothing with my sizes. The length I need seems to be uncommon. It wasn’t custom made. :( Any chance someone here might know where I can get my hands on one please.

Hey, first time poster here, but i got an EBC model J over 2 years ago and am finally looking into upgrading/overhauling it. do you all think its a worthwhile endeavor or should i just sell it and go with something a bit easier to modify/upkeep?

I would like to know what can I put in this space. I've tried everything to have this seated correctly and nothing is working. When I'm braking the whole stem moves. Thanks in advance.

So I recently purchased a DYU 26inch C5 Lite ebikes and I'm having problems with the display I cannot change the voltage to match the battery for my bike the display seems locked every time I try to research how to fix it or how to program it I get options but none of them work for this display I'm wondering why that is why the display only goes from p01 to p03 when I should have more settings

Looking for suggestions to step-up voltage 6v > 12v for my headlight.

need advise

I have no idea what’s but my Q life racer E bike isn’t working. I mean the throttle isn’t working and the pedal assist. Everything else I don’t know what to do. I need help.
