i always considered the 2000 to 2006 Giant Lafree with it's through crank drive unit one of the best 24V pedelecs out there. too bad Giant spent so much time screwing it up after 2006.
for lots of tips on how to deal with this bike try this website:
tons of info on the bikes, how they work and what bits can be repaired. also how to change the drive sprockets to get either higher speed or torque.
personally i think that they mostly got it right (for a EU spec 250W bike) and only missed the boat by not offering the Shimano AI-4S35 Auto-D electronically shifting 4speed hub as an available option. they also should have offered a higher power North American version with a higher speed limit. Likely would have gained more acceptance then. but all in all this was a good unit.
