The seat height was taller than I thought it would be. Im 6ft 2in and its the perfect height. Even pedaling (rarely) my knees dont look like Im riding a smaller pit bike or a bike made for a teen. This is made for my height as an adult. My wife is 5ft 8in and she says its too tall for her. Her toes touch the ground. The bike with battery is heavy, around 140lbs. Im also 300lbs and can get it to about 36mph on the 50mph setting, which is plenty for me. Its faster than anyone can run. I dont plan to use it to jump hills or ride wheelies. Its faster than it seems like it would be. It also goes about 20mph up a 10-15 degree hill. pedaling helps but isnt required. It handles off roading great. At night, the headlight has 5 settings; white, yellow, white and yellow, white strobe and yellow strobe. Luckily, I got prior approval from my local PD to ride on roads in the city and as long as I follow bike laws, they wont say anything. I normally just pedal past them. The only issue with that is no matter how slow you pedal it wants to reach the max speed for your 1-5 setting. I tend to use my breaks a lot. The chain is really only good when something dies. Pedalling uses a sensor on the left side to drive the motor. Something to note, the tools and missing parts came with my battery which arrived the day after the g300 pro. I had already put it together. Also, when charging, the charger gets hot even with the built in fan but the battery stays cool. Not hot enough to catch on fire. Also, if your new to e-motos like I am, you will want to lean into your turns and dont treat it like a mountain bike. If there is anything else, I will try to add it later.

I put 300 miles on mine so far and had it about a month. I'm loving it. I pass up every e-bike I ever seen on the road and this thing takes off faster than most cars at a red light. everybody stops and stares. The bike advertises 50 miles an hour but I weigh a little bit more so my top speed ends up being 47 mph. But it's very fast on the takeoff. As far as quality is concerned I had a 120 lb bulldog run out in front of me at night time because all my blinging lights and accessories the dog wouldn't move and I ended up hitting him at 10 miles an hour and dumping the bike. Dog is okay, bike ended up with a few minor scratches. Bought some black touch up paint today to take care of that. This is my 4th ebike and I feel like I finally made a decent investment this round. Happyrun.com has all the parts needed for this ebike if anything were to ever break down. That gives me peace of mind knowing that if something goes out there a few clicks away and I'll be on the road running again. Ps. If you like conserving battery stay in fourth gear at 32 miles an hour and only use 5th gear for showing out. My job's only 4 MI away so I'm at 8 Mile round trip everyday and I can literally drive this thing for a week straight without needing to change the battery as long as I'm in 4th gear. If I use 5th gear however I have to charge every day - every other day. Also, Nilight® accessories not included

Great Moto bicycle crossover bike, the pedals make it easy for in town commute without law enforcement engagement. I’m going to replace the throttle and grips, stock grips and throttle twist are inconvenient. Great frame and structural integrity. Rear shock coil spring makes noise, mounting bushings on rear shock inadequate there’s at least a 1/2 inch play/slop. All said this is a great starter emoto bike for the price !

This thing is painfully slow. I got it to go 50 mph, but it’s a ridiculously slow build up. I’ve got to figure out how to return this POS

Just purchased the blue model. Although shipping took longer than what was promised it did arrive intact. The build quality is amazing. This bike is worth the cost. It is quick and handles well. The pedals did bind up after driving it for 1 mile but I took it back home and adjusted the back tire and all was good. Shipping from amazon showed the package at 31.7 lbs which scared me. But that was the battery shipped in a different box.

Very impressive for the money definitely helps having an extra pair of hands putting it together.
