Ok so i took this bike from charles hurst yamaha in belfasts boucher road branch(find register for test ride link at bottom) and from the start it was clear that they didnt know much about mountain bikes or mountain biking in general (motorcycle sales reps and mechanics) so i took the bike and went to rostrevor just to get a feel for this bikes motor suspension ect and how it handled rocks, jumps, big berms and i took it on a high speed dh fireroad, there is some negitives with this yamaha brand which you see in this video but its not all bad. https://www.yamaha-motor.eu/gb/en/ebike/test-ride/mountain/book/
