Generally very pleased. The weight of the battery on the handlebars is not apparent when on the move. Only need the highest power setting on the very steepest hills. Normally I use the lowest setting. Had to increase tyre size from 700x32c to 700x35c due to the extra weight and performance. On my hybrid bike the front wheel rim came apart due to brake block pressure. A local bike shop eventually sourced a rim and spokes and rebuilt the wheel. Would not happen with disc brakes! I said I would never get an electric bike but my wife got one. I could keep up on the level but not on inclines. The Swytch kit lets me keep up. I am in my seventies and the kit makes in easier on the knees (wear and tear). If I go for a ride I find I am going 25% further than without the kit.
