Rider Reviews
Puts the PostJoy GT50 through a hands-on road test and presents it as an adventure-focused electric bike rather than an ordinary commuter model. The review highlights its rugged, motorcycle-inspired styling, responsive power delivery, bright lighting, and confidence-inspiring ride, making it an appealing option for riders seeking a distinctive electric dirt-bike experience.
Reviews the PostJoy GT50 as a highly affordable retro motorcycle-style commuter e-bike priced at approximately $799. It reaches a tested top speed of 34 mph and stands out for its stylish appearance, responsive handling, and excellent value. However, its initial torque and hill-climbing power are relatively modest, making it less suitable for stunts or aggressive riding.
Tests the PostJoy GT50’s 750W motor, front-and-rear suspension, and real-world riding performance. The review praises its comfortable saddle, effective suspension, and strong overall value, while noting its heavy 93-pound frame and the use of a hydraulic brake only on the rear wheel.

FAQs
Q: Why does the tire show 16 instead of 20?
A: The “16” on the tire sidewall refers to motorcycle-style rim diameter, while the product page lists the tire’s approximate outer size as 20" x 3.0". These are two different tire measurement standards.
Q: Are the GT50 tires suitable for off-road riding?
A: Yes. The GT50 uses wide 20" x 3.0" motorcycle-style off-road tires with aggressive tread, suitable for gravel, dirt trails, mountain roads, rural roads, mud, snow, and pavement.
Q: How far can the GT50 go on one charge?
A: The GT50 offers up to 80 miles of range. Actual range depends on speed, rider weight, road conditions, throttle usage, assist level, and weather.
Q: How long does it take to charge the GT50?
A: The GT50 battery usually takes around 6–8 hours to fully charge.
Q: What is the maximum load capacity?
A: The GT50 supports up to 365 lbs of maximum payload capacity.
bike does not got 40mph still a pretty cool bike for 820$ everyone loves how it looks goes problee 33 mph top i weigh 175 5’11 you can go maybe 45 miles tops before needing a recharge
Honestly great quality just the battery isn’t that long and the speedometer is so wrong and beautiful tiers.
Its a nice bike looks great rides smooth and has plenty of power im 6'1 230 so it moves me very well with no problem def recommend
Awesome bikes
I use this bike for short commutes and some weekend exploring. It rides well on pavement, gravel, and packed dirt. The hydraulic brakes feel responsive, which is important because the bike has some real speed. I like that it comes with lights and a clear display. No major complaints so far.
I wanted something stronger than a basic commuter e-bike but not a full motorcycle. This fits that middle ground pretty well. It has good pickup, rides comfortably, and feels capable on mixed terrain. I wouldn’t call it small or light, but for what it is, it rides nicely.
For the price, the specs are pretty impressive. The 60V battery, strong motor, full suspension, and hydraulic brakes make it feel like a step up from entry-level e-bikes. I mostly ride on back roads and trails, and it has handled them well. I would recommend checking local rules before riding at higher speeds.
I’ve only put a limited number of miles on it so far, but the first impression is good. The bike feels stable, the tires grip well, and the motor has more than enough power for my needs. It’s a large and heavy bike, so make sure you have space to store it. Overall, I’m happy with the purchase.
Bike broke
Well up to 80 mile range battery life is a lie i don't use throttle at all and ride pos 3 it won't even go 25 mile. My pedals are already making noises. First day for it couldn't get back tire hold air it was faulty tube had buy that 55 bucks. Now I'm need buy extra battery just to be able ride it long enough to hopefully have fun on it
I'm actually disappointed with the bike
Good build quality, fast bike. Only issues I have is there is a three second delay on the throttle on and off. So when you start pedaling it takes about seven rotations before the assist kicks in and when you stop it keeps going, same with the throttle. The front fork need more of a rake so it can be steered, it’s more of a lean to turn.
My 14 year old son loves his new bike. He is tall for his age 6'2 and it fits him just right
I gave it a 5 star because that is what it is on the outside when really, it should be 2 star. I love the bike and it is everything I was expecting. Would I buy it again? Probably, here's what's up. 1st it is very very difficult to get on or off the bike. The rear fender is sticking up to much and has caused me to fall a couple of times. The suspension doesn't work at all. It needs a better rear shock. In high speed the bike gets wobbly and I felt unstable at high speed. I put my own rear view mirror on because to look behind me is way to unsafe.My final thought is to warn everyone that really the bike is unsafe to ride in it's current condition. To fast, and please wear a full face helmet, regular bike helmet isn't enough.
Bought the GT50 for someone and they love it so far, charges fast and does everything it is supposed to. He loves just hopping on and going. Only downfall is that it shouldn't be driven in the rain. Would recommend
We love the bikes . The only issue is I do not believe the battery life is as long as they claim . We rode them like30 miles and the batteries were almost dead . Customer service is amazing !!!
If only the battery would last a bit longer,but other than that it's really nice,rides smooth
I’ve had the GT50 for a couple of weeks now and it has been solid so far. The motor has plenty of power for hills around my area, and the acceleration feels smooth once you get used to it. The bike is heavier than a regular e-bike, but that was expected with this style. Overall, I think it’s a good value for the specs.
So far the battery has been performing well. I haven’t tested the full 80-mile range, but for my daily rides and weekend use, it has more than enough charge. Charging usually takes several hours, so I just plug it in overnight. The removable battery would have been nice, but overall I’m satisfied with the range.
I bought this mainly for riding around rural roads and some light dirt trails. The suspension does help a lot with bumps and gravel, and the wider tires feel stable. The seat is more comfortable than I expected for longer rides. Assembly was pretty straightforward, although I still took my time checking all the bolts.
The GT50 feels sturdy and well built. It has good torque and handles hills better than my previous e-bike. Just keep in mind it’s not a lightweight bike, so moving it around in a garage or lifting it is not easy. Once you’re riding, the weight actually makes it feel stable.
The bike arrived in less than a week and was packed better than I expected. There were no major scratches or damage. Setup took me about an hour, mostly because I wanted to make sure everything was tightened correctly. Customer support answered one question I had about charging, so that was a plus.
After riding it for a while, the two things I appreciate most are the hydraulic brakes and the suspension. The brakes feel much better than the mechanical brakes on my old bike. The suspension makes a noticeable difference on uneven roads. The bike is powerful, so having good braking is definitely important.
