Bike has more power than you think with maximum boost taking me up a hill at 16kmh when I had to walk up with my old mountain bike. solid bike but is a bit heavy Im guessing thats just how these bikes roll. Head light is super bright but has no tail light such a shame. Gears sometimes miss a gear but this is an entry level bike. some of the spokes on my back wheel were loose and rattling I just tightened them up enough to take out the slack so no biggy. If not for the spoke issue 5 stars. Im a fat bugger so the 150kg load rating is handy I can even carry a few things with me. I only ride short distances for now to and from work but looking forward to longer rides. Actually a low drag ride with tyres at full pressure and speed for assistance can be raised not legal to give a smoother transition to no assist.
