    road bike frames for electric conversion

    Thanks for advice, I will try it. I will sort the brakes out even though I am not a speed merchant, I just need more help with hills. I bought the bike at a car boot, the decalls had been taken off. It looks like a 531 label on your frame in your pic? The drop outs do look a bit thin but then...

    Need new battery where from please?

    I need a new 36v or 48v lipo, 11ah or more. Size,appearance and key lock not important. A compact size would fit in my pannier bag better. I understand re-celling is not a cheaper option? Anyone any suggestions please? Thanks, Mike

    Hi from hilly Sheffield

    Hi d8veh I burned my finger on the main terminals. Re, getting wet, fairly sure not as I rarely went out in the rain and I always carry the battery in my pannier bag.
