— AnonymousGreat bike

— Cheryl OssolaI love it! I’m 5” 2 but can handle it fine
Received my BG-X in 3 days, Packaging was done very good & thought out, Bike was fairly easy to put together. I have ridden the bike 20 miles as of now feels great, real sold looking forward to using it more !
— Anonymous Great Ride !
Very happy with the bike... seat was to low for my height.. I put on the height enhancement seat and it is better but takes away the sleek look.
— James WinebrennerVery happy with the bike
I’m glad I held off so long before pulling the trigger on purchasing an e-bike! The BG-X rocks - sure it’s heavy, but it’s solid, and it looks very cool - a head turner!
— Wayne PetersonGlad I was patient!
You can still pedal it - one speed only, but you still get a workout on your legs as you’d like, yet it has speed and endurance for the fun of it or commute. Also, I love the idea of being able to sit in the saddle and have both feet flat on the ground.
Highly recommend.👍🏼👍🏼
The only problem I had with the bike was the front and rear fenders. The are completely useless for passing through water or riding in the rain. I still have a blast every time I get on it and it is definitely worth the money and effort especially if you live in a moderately dry place.
— Joseph HernandezGrate bike but front and rear fenders are useless.
When I seen this Bike, had to get me one. I have four chopper bikes, one with a 80 cc 2stroke on it. I got 4200$ in fines on the motorized one. Because they outlawed gas motorized bikes. But now I am riding a electric bike that conforms to the law. I'm really in love with this bike. 💚
