How reliable are Gtech bikes, and would there be a problem with spares. We have a couple of A2B folders, which are ok. A couple of friends have shown an interest in e bikes, we loaned them ours for a week, but they did not like the small wheels at all. They tried a Batribike full size, weight put them off. The Gtech City and Sports models have taken there fancy, not to heavy, would be able to use on bike rack with batteries removed, and they like the fuss free no gears. I will say the bikes look very tempting, and for what they would use them for should be fine, there both into mid to late 60's, reasonably a bit on the chubby size. The 14 day trial looks a tempting offer, but I'm not sure on spares or reliability, we've had Gtech household / gardening products for years with no problems, but the bikes are something completely different. Any advice appreciated.
