Anyone familiar with the electric bike kits of Cyclone ? They look a lot like those popular in Australia. The ability to send power through the chain and use the gears of the bike (without the addition of a gearbox) is interesting ... anyone have experience with these that might care to compare them with a BD or BL style hub motor ? Not asking anyone to say one is better than the other for I realize each has it's strengths and weaknesses - but a nice discussion would be very informative ... how are they with more volts ? how are the components in terms of durability and ease of use ? are they easy to hop up or are they "performers" right out of the box ... any tips/tricks/particulars worth noting ? How long was the install ?
