The best value eMTB on the market

I've been riding and testing various hub motor and mid-drive eBikes and the Copperhead EVO HD750 is easily the best value hardtail eMTB. The Bosch Smart System is the best motor/battery system for e-bikes I've used. Plus, I like that the batteries are UL tested. Bulls spec'd this bike to be an ultimate eBikepacking monster, with the 330LB weight limit which is great for me being a 290lb guy. Even with my heavy weight I completed a 40 mile 4000ft+ ride with 10% battery remaining. I love it!!
