The topic of electric bikes is completely unknown to me, but I bought a BBS02B 48V 750W 25A motor yesterday on a promotion in the store on AliExpress, because I read, that this engine has the ability to program the driver through the BafangConfigTool program.

I have ordered the 48v battery 800 watts is plenty so will reduce the ams to. I wouldnt mind trying a mid-drive but I keep hearing that they are harder on the bike. Hi Tony! Triple the number of recharge cycles on the most expensive disposable part. What is your take on rear hub vs mid drive for Fat Tire bike build? It would definitely be worth getting a 36t Lekkie Bling ring (or similar) to keep the gearing low or fit something like an 11-42 rear cassette. Its definitely better to have the lower gearing, I have a 25% climb near me and having the lower bail-out gear gets me up there without any fuss. The 750w version is the most popular as it offers the most bang for your buck! Any idea which Schwinn models use the 68-733mm bracket?

This includes limiting the speed and power when riding in urban areas and riding carefully and not at excessive speed in public places. I am concerned about how little room I have in the area where it comes close to the chainstay. Also, is the 500 watt version more reliable than the 750 watt? Or is there anything I can do in the programme so I can keep up with my bike? If you want to put a cherry on top of that get a Gates belt drive and have a better ebike than any production ebike on the market today. I have experienced a couple of issues, where the part has never been returned or has somehow got mysteriously been lost in the post. Lithium batteries tend to lose around 20% when the temperature dips below -10. Youre welcome, glad to help. Having a hydraulic brake on the front would be better, but good quality v-brakes should do the job in dry weather. Any help suggesting the best set would be much appreciated.RegardsNigel.
