I have a Bakcou and can say it's a beast!  Yes, it is expensive…but, like anything else you get what you pay for, and most will opt for cheaper…they have more problems, and I don't have time to deal with problems during deer season.  You miss one hunt because your eBike is down and it could be the morning that shooter visits your stand.  Not that all new eBikes aren't reliable, but how long will it be before you have issues.  Bakcou is designed and built by hunters.  I have the Bakcou Storm and zero regrets about spending the extra.  Whatever your choice, best of luck!
