After having to pay out for tow bar and Thule bike rack I have had to cut my bike budget, looking more and more at Woosh. The crank drives interest me, but I see a fair few coments on poor gear changes on Woosh crank bikes, only crank drive bike I have tried was test ride on Gepida berig 1000 with Bosch electrics,and that was fine . Would I have probkems with the Woosh system, what is build quality like on Woosh bikes, I know there not up to Kalkhoff build, but you pay for that. I'm not against hub motors, but being 16 stone, 5' 9" they keep recommending crank bikes or the Big Bear, latter looks way to bulky for me. Any advice on Woosh or other bikes appreciated, under the £1000 bracket please. Thanks
