I'm in need of good sound advice as I've got a mountain bike with step through frame and 26 inch wheels and I want to find a reliable E kit with rear wheel drive. I have fitted derailleur gears already with the necessary handle bar controls and brakes. I have no idea what kit to purchase for me needs, Mostly on road, NOT off. My age doesn't need endurance riding But I'm quite capable of any mechanical work needed to complete the project. What kit is recommended by the members here? I will need peddle assist and a range of maybe 30 + miles or more between battery charging. I've been looking far and wide for some time now to find everything I need to continue and been disillusioned by the other peoples reviews on many concerns with products and after sales service. I need a total cost of everything I will need, and not forgetting battery and charger etc from a well known reliable company. This project is very important to me, especially now I'm alone and a widower, to help life to be worth living. I look forward to any replies. Thanks in advance.
