Just clocked up my first 100 miles on my new Kalkhoff Impulse 8 electric bike. If any Funsters are thinking of buying an electric pedal assist bike I can thoroughly recommend thes bikes. The latest being a belt drive, quieter, no maintenance and lasts 5 times longer than a chain. The new battery on ECO Mode has a range of 120 MILES. I am 15+ stone and realistically it looks as if I am going to get around 90 miles Eco, 45 miles Sport and 30miles on high assist. These bikes are not cheap but really are the Rolls Royce of electric bikes. Just another bit of information, as from April this year TWIST AND GO Electric bikes ie if you are not pedalling assistance will be illegal bringing us inline with the EU.
