That is some price to pay for a Bosch Kalkhoff i know the Kalkhoff is a class bike but how they expect to sell the 2012 range at that price well i thank they are over priced i would not pay the price no mater how good they are.
Bosch replacement batteries about 5-600 euro. the cheaper model Kalkhoff Bosch S class was approx £2450 last time I looked. the new Panasonic 36 volt S class over £3700 and Sahel models £3300...... I cant check as computer speed problems, but you can look at euro prices on this link:
Kalkhoff : 2012
David, the Panasonic crank drive bikes have been around for ages, the Bosch crank drives are very new. if you want a throttle powered bike you need to get a hub powered bike, they are cheaper as well.....
