Title: Great product especially for the price!
Review: I haven't had much time on this bike with this motor, but I really enjoy it! Seller conmments below. This review covers what I currently know. I intendto update when I know more. This really is a great product! It can turn most bikes into an comparable e-bike. That being said, it's universal application makes it difficult to translate for every use.This kit was very easy to install. Keep in mind you will need the right tools. The only real potential issue I see it the main cable length is a bit shorter than I would like. A Bafang extension will work. I was able to make it work for my installation. It's worth mentioning, make sure that The output doesn't make contact with the frame. I only had about 0.5 mm of interference, but it was enough to cause chain problems. The spacers in the kit were perfect for my needs.When compared to the Bosch power bike rentals I have experience with, this motor seems to have much more power. My display is limited to 1kw, and when the demand is high it will exceed 1kw quickly. I have a 9-speed with a 36 tooth first sprock and on PAS 5 this bike will pull wheelies with firm pedal inputs up hill. The torque sensor works great! The firmware could use refinement though. The only real issue is the motor lag on and off. Once activated it's fine. I wish it could be adjusted. However this minor trade-off in safistication is well worth the price you pay! It is also a is a common safety feature among e-bikes. After all this bike will wheelie suddenly in low gears.I feel very confident in saying this would be a great commuter, with one caveat. This kit needs more chain ring options! It's capable of doing 30 plus miles an hour but you will be pedaling very hard to sustain that. This is mostly due to the torque sensor. If you can't keep enough force up at high RPMs, it limits your speed. The motor is capable more.This would be also be a great addition to a mountain bike. I would recommend caution on crazy rough terrain. The wires exit from the bottom of the motor. There are now a chain ring options out there but it is 200+$. If that is a problem for you. I would only only change it for clearance. The motor has plenty of power but you would trade commuting speeds for clearance.I have not tested range properly but on PAS 3 you can achieve 25mph using about 300w or better. These are conservative estimates. My readout is not numerical. My battery is rated 1040kwh. That puts my puts my theoretical range conservatively at 70miles.Lastly my buying experience from Varstom was not the best experience. They contacted me asking what sensors I wanted and to tell me my motor was going to take more than double the shipping time. I asked for a realistic delivery estimate and told them what brake sensors I wanted. I chose them at nearly 90$ over the competition, because they boasted faster shipping. They took nearly a week to get back to me, and didn't send me the brake sensors I asked for. I believe they were intentionally avoiding my inquiries about shipping time which worked out for them. Also they messed up my sensor choice. It would have taken nearly as long to ship from China. I don't believe they cared enough to make it right so I am putting this 90$ sting on their reputation instead. For what it's worth...

Title: Anti rotation and additional programming
Review: I have not bought this yet. I still have unanswered questions. Open software. Does it require programming. I want plug and play.Have ICE trike. Without anti rotation mount motor would turn upside down. Need answers.
