Conversions of motorcycles to electric power can be very successful although it is hard to retain high levels of performance unless significant sacrifices in range are accepted. Lead acid batteries can only provide ranges of 20 to 30 miles, so it is generally necessary to use lithium batteries to achieve ranges of 40 to 80miles depending on battery specification and driving speed.
Because of the difficulty of concealing sufficient batteries within the original shape or fairing of a motorcycle, machines converted for a higher speed or range generally have to have a modified shape to accommodate the battery and motor.
The costs of conversions varies enormously depending on the range and performance required. Motorcycle conversions suitable for modest city commuter applications can cost as little as £3,500 plus vat. 120mph high performance machines with a range of up to 100miles at more modest speeds can cost ten times this figure to convert.
