I have had two years experience riding an electric bicycle. I own a Woosh Zephyr CDN. I am now wanting to change to a full size (below £1000) bike and have been looking at the Big Bear. My Zephyr CDN is great, it copes with all hills brilliantly and is reasonably comfortable. My new bike would have to pull even better and have improved comfort. I am guessing the Big Bear will do so? One thing which i have been giving thought to, the front wheel motor, will i be able to hear it, being as it's in front of me? My CDN is silent, i don't hear a thing. I would also like an upright seating position so i would like to change the handlebars for ones similar to the ones on the Big Bear LS. Will the front wheel lose traction if i do so, as there will be less weight over the wheel?
