Riding the eBike really delights, way easier to pedal uphill; much faster ride times; fun. My only concern was leaning down and forward a little too much. I looked into that and found a solution – a light adjustment to the reach length. I went to REI for a bike fitting check and they affirmed my seat and handlebars position was OK. So I felt this little adjustment pulling the handlebars up and in a hair would be. I picked up a slightly lifting stem to replace the flatter one that came with the Yamaha. See it here:
I needed to avoid lifting the handlebars up too much higher because the brake levers are attached with hydraulic tubes to the hydraulic disk brakes and I did not want to have to lengthen them.
