Amazing Bike, Even More Amazing Customer Support
Many reviews sing the praise of this bike so I won't have much to add other than confirm. HOWEVER, I can add one angle most don't get to write about. My shipment had one part that was not perfectly machined and a bit clearance was missing - The HappyRun team dotted over me and my problem, shipped replacements provided video they made at the factory to show me how to address it. BOTTOM LINE - you not only will get a great machine but you get a team behind who cares. Thank you HappyRun. This is my 2nd bike with you and now surely not my last.

New e-dirt boke
This bike is all that it claims to be! 49.2 miles an hour. The body is very sturdy. This bike is heavier than I thought. This bike has power you can move in traffic cross streets and not feel like a target or a turtle.

Better than I expected
I haven't used the G300 Pro long enough to say anything about it's reliability or durability. What I was able to test thoroughly was it's functions with lights and signals as well as overall distance. Plenty of torque, rides nice and feels very comfortable even for a 275lbs guy!
