Ok that's fair enough, I actually almost never switch my ebike motor on unless I need to get somewhere real fast ,But the option is there if am having a bad day or there is a strong headwind etc. I find that riding around with the extra weight of the motor and the battery does wonders when I ride my non powered bikes with my mate on the weekend. Good luck and enjoy your ebike when you get sorted,you wont regret getting one Paul

Hi Have a search for Bafang BBS01B mid drive motor kit , This is a 250W motor that fits into the bottom bracket of your existing bike, It is possible to convert a bike in about 2 hours with fairly basic hand tools . you should be able to get the motor and a decent battery 36V 15Ah for around £600.

Hi I had a similar problems in the past with my cassette. There are commercial tools available to check for sprocket wear,but I check mine with the blunt end of a 10mm twist drill bit . If the sprocket is in good order the 10mm drill bit will fit snugly in the valley between the teeth and will not rattle side to side. Try it on a gear you don't often use for reference. If there is anything more than a slight bit of play your cassette is on the way out . I change my chains at 0.5% wear and find the cassettes last a much longer. If you dont fancy the 10mm drill route,putting a new chain on will confirm a worn cassette , the new chain will jump more than the old one did on a worn cassette. If your chain and sprockets do turn out to be OK , the ratchet in your free-hub may be slipping occasionally this can feel like your chain is jumping. Anyway good luck Paul

Hi All I Put my ebike together about a month ago really pleased with it so far. Had to make up spacers for the BBS01 and fashion a chain tensioner but apart from that pretty easy. Paul
