Super fun buy - im also a large guy

This Ebike is incredible for the price. Assembly definitely took some time and some patience. Watching videos alongside reading the instructions helps tremendously. Minor adjustments as expected. Some of the factory driven bolts are TOUGH to get out. The LCD screen was cracked on the back of it out of the box but customer service sent me a new one the next day. Im 6 foot 2 inches and an active 330lbs. This bike supports me like its nothing. Out of the box it reaches 20mph, with the top speed mode, i was holding at 28mph. Its an absolute blast. My spouse rode on it with me, together were about 440lbs, and I reached 20mph still. I had a buddy of mine hop on with me, together we are almost 600 pounds, we hit 19mph. This things shockingly powerful and the maneuverability is great. The headlight is powerful, it has a taillight that flashes when you brake. It has blinkers. All in all one of the coolest buys ive done in a long time. Im trying to find excuses to leave the spouse and kids to go cruise around on it.

Perfect!!!!

Epic Lil Bike. Can't Stay Off Of It. Not Only Is It Perfect For Commutes But Riding Around On Trails Is A Blast. The Standard Leaves Alil Room To Be Desired On Battery Life But That To B Expected. Planning On Purchasing The Plus Battery And Poping That Sucker In. Should Take Care Of That. Also Can't Wait To See How Well It Does On Longer Trips.

Great Power

Very sturdy, and has a great speed. The bike is big enough to hold two and it fits me and my wife. Took a while to put together but this is my first electric bike. The brakes work well and the turns are easy to make.
