Evil Knieval was every kids Idol back in the day...I believe Aventon has been in the game for a while making racing bikes (road cycles) they have 4 or 5 ebikes on the market. Chinese made but very good quality components. It has manual brakes, hydraulic would give it the stopping power it needs (70lbs. total weight). I just purchased a month ago and don't ride on wet roads so I have taken it out about five/six rides. I'm having an issue with the derailleur getting into 7th gear. I read in another post someone mention a grinding noise. Someone said it might be a bad hub. So fearing the worst I ran it on a jack stand in my garage and notice the noise I have is when I have it in pedal assist trying to shift to top gear.
If I can adjust the derailleur I will be a happy camper. The bike is a beast besides the shifting issue. Hills, terrain not a problem for 5'10" 200lbs.
All I ever wanted to do as a kid was ride dirt bikes and snowmobiles!
