i bought this for my 9 year old daughter for christmas!!!! it was a hit... she loves it.... i went through every bolt.... loc-tite and tightening everything down...made sure the front wheels have the proper toe in, oil the chain and make sure its not too tight and away you go!!! used it twice so far... 2 hours each time... stayed at 4 bars of power each time... no complaints there!!!! i even ripped around in it... a little tight for an adult, but the kids enjoyed seeing me wheeling it around... hahaha

as the other reviewer stated, because its posi-drive in the back, it will push in slow speed turns especially with a little one in the go-kart... there are ways around this... just need to pull the king pin on the wheel, opposite of the motor.. easy enough, good for pavement use... but off-road you wanna keep it with both wheels motoring you along...

this is the second motorized vehicle i have purchased through UPZY... not a single complaint about this company... they get 5 stars and 2 thumbs up from me...

Very easy to get this up and running. Just had to install handle bars and charge it for 6-8hrs. Quality frame and tires. My 3yr old was off-roading with ease (even went in some mud). She loves the pink color. My one recommendation is to remove the foot pedal kill switch first thing before your little one rides for the first time. Just disconnect it from the controller and remove it from foot rest (remove 5 screws and snip the zip ties then reinstall the foot rest). With her tiny feet she couldn’t keep the pedal engaged and was just something else to complicate things. Once I took that off she rode it like a champ. For how much this costs it’s a great investment. Upzy was cheapest place to buy and that was before I used a promotional coupon.

This ride put me right in the scooter business. A fellow Veteran was able to travel again after 2 years of being stuck in a wheel chair. When he got his after riding it he cried. I have sense helped many with mobility issues. I can't thank you guys enough. Cary, Vancouver WA.

i had a few Goped GSR40'S(Not the TSI version) and they were pretty quick at 35-40mph but i wanted something a lil faster,so i got the smaller framed GSR25 and bolted a gsr46 engine the CY460 and right out the box,i did 49mph with just a gutted stock muffler and tuned the carb good & ran 9/64 gearing,it took awhile to get to that speed though lol but still very fast.now i built a GSR46R with an ADA Racing 13.1 compression head kit,ADA Racing +1mm stroker crank,ported the cylinder and flow ported & stuffed the crank case myself running 8/68 and i haven't done a top speed yet(still breaking in the new engine)but it has a lot of torque and gets up to speed quickly! anyhow i recommend you buy this GSR46R here cuz it's a good price and modify the engine later to make it even faster,unless u wanna build a fully customized GSR46 like i did but it will run you over $1,700 bucks but it will look like a show ped.it's up to you.

Fast delivery, fast response time and great customer service! My package initially shipped with some missing parts but UPZY team resolved with a follow up delivery within a few days. Couldn't be happier!

Love my new bike. It's exactly as advertised. Thanks again!!

My dog loves this thing. I love this thing. My wife loves this thing. Everybody we pass on the road loves seeing us use it. It is sturdy, comfortable, easy to maneuver, and has all of the bells and whistles to make you and your dog feel secure and comfy on bike rides together. All other bike trailers pale in comparison to this Dutch-designed beauty.

Purchased a bike that had an issue with the back rim. The bike was shipped from the manufacturer and not Upzy, so technically his was the manufacturer’s issue. Upzy still went ahead and called the manufacturer, who then contacted me directly and resolved the issue. They went out of their way to help.

I am SOOOOOO happy with the bike rack I purchased through Upzy!!! It was delivered on time and it’s the best bike rack around!!!!! I highly recommend this bike rack if you have any electric bike with fat tires!!!! It’s VERY sturdy and I HIGHLY recommend Upzy!!! Love it!!!

If you're looking for your first recumbent trike you can't go wrong with the JC-70. I really didn't know what to expect, but when it arrived and I put it together I was looking at one beautiful trike. The paint job (mine is golden orange) is top notch.
I chose the XT version so I have a few upgrades but I don't think it really matters when it comes to quality. The components aren't the most expensive, but they certainly aren't the least either.
I'm in the process of installing a Cyclone 3000w 72v electric motor for those uphill climbs here in Central Oregon. All I can say is the combination of the JC-70 and the Cyclone 3000 will make one heck of a e-trike. Couldn't be more pleased!

I love my Nakto electric bike. I like to zip into our local resort town to see what’s going on. I don’t have to worry about finding and paying for a parking spot. The bike arrived on time and all I had to do is unpack it, unfold it, tighten a couple of things and go. I am the envy of my campground. My sister already bought one, and I’m sure there will be more orders. Thanks UPZY.

Using the pedal assist "NAKTO" bike is harder --than, I thought it would be! I use the pedal assist for exercise. It takes me a few more pedal rotations on my bike to be in perpetual motion. My legs work to hard on the pedal assist bike. The battery and charger work just fine after each initial test. Please understand, this is a brand new product that should be in good working order.

Gave to wife for anniversary. She rides it every day.only problem battery doesn't last long enough gets only arround 9 miles on peddle assist.

Been taking a few rides to get acquainted. Very smooth on the road and gets even more fun as you get into the off road trails. The motor is strong and the upgraded Wren suspension a pleasure. The 21 ah battery is a definite plus. Overall, decently built and a fun toy. The Upzy team was a great help in getting the order facilitated with Biktrx.

My husband owns the Sport G4, and after using it a couple of times, I ordered the City Bike. I like its smaller size and the basket comes in handy. We enjoy kickbiking together. Great aerobic exercise and kick biking also strengthens and tones your lower extremities.

Quality construction and easy assembly. Can't tell it is behind the bike.

Had a bunch of questions and spoke at length with the upzy team before pullin the trigger and getting the DB14. Researched a bunch of different sites before deciding to go with upzy cos they had the best prices.

This dirt bike was for my kid and he loves it! Might consider getting one myself, maybe the DB27? hehe

This scooter is built like a tank. It’s able to get me to work (3 miles on a paved trail) oe 20-40% of a charge going 18-22mph the whole time. That’s pretty reasonable given I’m over 200lbs and the 20 mile range is rated around 12-15mph. I would appreciate a little more torque to help get up hills, but I don’t mind to help it out with a kick every now and then. Overall well worth the price
