Can 6.5HP motor power a tandem bike?

Hey folks, in this video Kim and I put a predator 212cc engine on a tandem two-seater bicycle! it is a super cool build and it was a lot of fun to ride the motorbike together! The bike tops out at maybe 25-30 mph, and has plenty of torque to take the two of us anywhere. If you liked the video of this bike be sure to check out the channel for other projects such as mini bikes, go karts, gas scooters, motorized bikes and motorcycles!
