Bike is great, easy to use. Particularly like the 'accelerator' to help get going on inclines and to push it up hills. Used it 3 times so far. Unfortunately on the last occasion on a canal towpath, the back wheel slipped sideways, I crashed into the bridge, the bike and me fell over. End result was a trip to A&E, x rays, painkillers. Ultimately resulted in spinal surgery a few weeks later. Think there needs to be more caution given to riders about the possibility of this happening and what the consequences may be ( although I am sure mine are quite extreme!!). Another electric bike rider I was with experiences the same back wheel sliding but was better able to cope with it. Don't let this put you off having an electric bike, they are great, but do treat them with caution.
