The motor works fine, the installation was easy and pretty straight forward. Some bikes may need an extra tool for the front axle removal depending the type of the axle.

Everything shipped to Finland within a week. Very fast delivery! All parts were new and the motor is greased up nicely straight from the factory and operates quietly. Installation was fun and a great learning experience. Most difficulties occurred while removing old parts to make room for the motor. The screen's battery charge indicator keeps jumping up and down, but I suspect that this happens because the battery cells aren't evenly charged. This should be easily fixed by charging the battery to full. I recommend getting a better chainring. With the stock bafang chainring the chainline is awful and your chain will have difficulty staying on. I destroyed my rear derailleur because the chain skipped and got stuck while using the largest gearwheel. Luckily I had a spare lying around. Now My derailleur is tuned in a way that the largest gearwheel is not used.
was my first time fitting up one of these kits went with 44T did run into minor problems when mounting battery - holes didn't line up (no fault of kit just bike I had) but I just made adapter plate instead of drilling frame. unassisted speed is 50+kmh and has heaps of torque received kit in 7days highly recommend.
