Description

When the first GT73 off-road electric dirt bike crushed its way up a gravel slope, sixteen-year-old founder Storm Ryder gripped the throttle to the limit. Blue electric arcs danced across the dashboard, reflecting off his mud-splattered face—this Frankenstein’s monster, cobbled from scrapped motorcycle parts and drone batteries, roared as it tore through the boundary between city and wilderness. Just unboxed the GT73 and immediately hit the trails—this beast lives up to the hype! The dual-battery system delivers insane 2500W power, launching me from 0 to 35mph with heart-pumping torque. Cruised mountains for hours, and the 155-mile range still left 30% juice at sunset. The electromagnetic brakes? Flawless on steep drops. Worth every penny for thrill-seekers! Rain or mud, the GT73 laughs at limits. Took it storming through flooded trails—those knobby tires grip like glue, and splashing mud just amps up the fun! Dual batteries erased range anxiety; three-day mountain trips on one charge? Easy. Plus, its mech-inspired design gets stares everywhere. Teens’ ultimate flex-mobile? Certified. The GT73 electric dirt bike is thoughtfully designed with a storage bag between the two batteries, specifically to solve the problem of where to put your phone. You can choose whether to paste the stickers on it or not. If you have other design ideas or personalized concepts, you are welcome to freely unleash your creativity on the GT73.

I have had this bike for several months now. I have put over a hundred miles on the odometer and have had no issues. I did have Hiccup when the bike was delivered. As I was assembling the bike one of the bolts the front axle bolt to be precise had messed up threads. I had reached out to customer service And they Supplied a new one As well as a little sorry for the inconvenience. When received the parts I installed them and Everything fit like it was supposed to. Most of my writing has been on streets and sidewalks and I still have little nipples hanging off the tires because the tires are high quality is well. Admittedly the bike did feel a little cheap but don't let that fool you this thing is built well. I am a grown male adult weighing about 220 lb. My average speed on a flat surface is about 35. going down any kind of Hill means I go faster. Going up not steep hills my average speed is about 27 to 30. Any kind of major Hill climb It definitely bogs down and I'd be lucky to get over 15. The bike is also very comfortable to ride around as long as your road isn't full of potholes and bumps. Medium to large bumps and potholes cause me to bottom out every time. But if you stay on good roads it's a nice smooth ride. I did achieve the top speed of 50 but I did have to go down a pretty good Hill. I can tell a lot of thought went into designing this bike because you can charge it without having to remove the batteries. The overall Comfort while riding the bite is great and you can tell it was built with good strong quality materials. The one thing I would change are the factory pedals I wish they were a little more aggressive in terms of the grip. If my shoes get wet they are sliding all over the pedals. ... show more

    • An extremely well made and dependable bike especially for the price
Color: Black
I purchased the GT73 Electric Dirt Bike for my grandson. To begin with, when it arrived I was absolutely amazed at how well packaged the bike was. There was absolutely no room for movement or damage to the bike in transit. I have never seen anything packaged so well. It was fairly easy to assemble (especially with the assistance of the suggested video on the shipping carton). It is very well constructed, a great size for the price and appears extremely durable and able to be used on trails, especially with the sturdy and well-constructed tires. It has great pick up, is quick, stops well and overall, an outstanding product. I am not at all disappointed in this electric dirt bike. Well worth the money! ... show more

    • Great bike!

Review Image by Amazon Customer
This is a great bike. It fits well for a 14 yr old avg height kid. The batteries came charged so no waiting to ride. Just a minor amount of assembly, but it was easy to do, and all the tools you need were included. It has a solid body and a smooth ride.

    • Not for off-road
Color: Black
First off, assembly was easy and the suspension is decent. That is why it got two stars. This is advertised as a dirt bike yet struggles with even a grade when off-road. On-road, it does okay but really performs to the level of my son's friends e-mountain bikes that cost about half of what we paid for the GT73. If you are looking at this for your child, I recommend you look at something else. This is extremely overpriced for what you get which is an e-bike that will handle groomed, level trails with a 3% grade which is something that any hub drive e-bike can do. As I mentioned, the suspension is decent but is useless because this does not have the power required for trails, at all. Lastly, it seems he needs to run the batteries down to less than 20% for them to reliably take a charge. We wanted to return it but looking at that process and the fact he has ridden it, we decided to keep it for him to ride on the road. If you are not going to spend 2-3k on an e-bike, you probably will not get something capable of off-road no matter what their marketing has to say. These things are a gimmick and nothing more. ... show more
