Wellcome to the forum! I've preferred the DIY version kit, so I mulled it over after reading a good many reviews and came to the conclusion that a mid mount unit was the best for me at a lowest price possible, yet popular and with good performance. I purchased a Bafang BBS02 36V 500Watt and put it on a Huffy 10 speed which worked good except it's now a 5 speed what with the single sprocket.
