This is a review from John, who recently purchased and installed one of the SOLAR BIKE mid-drive conversion kits. We were a bit concerned about him using his own very small 4.4Ah battery but it seems to give him quite a good range.
HAPPY CUSTOMER. I just wanted to give some feed back. The motor I bought is just what I needed. The 4.4 Ah battery carried me on turbo mode in the morning and speed mode in the afternoon to and from work. I used the motor and pedalling for the 8.5 km journey. The battery needed a charge after this. Yesterday it used 25% battery capacity on the way to work. I Managed to hit speeds of 40- 50 km/h, though I can do this pedalling also. I will ask a friend to build me a water proof aluminium case for my battery and charger to fit in triangle. It took me 4 hrs to fit – inexperienced bike mechanic.
