You should take on some of my hills. I'm not going to say they are huge but I have hit 45mph in the past--these days, my sense of mortality has been kicking in. I rarely go past 35 anymore.My ebike came with headlite taillite brakelite and a loud horn. I'm in the sticks and just ride the roads. 25 on a bike is fast! And I've been 130 on a MC.
Again, downhill!
