BikeRide finds and shows you the best prices of the bikes you want to buy. Prices constantly change and it’s impossible to compare them all yourself.
We search for prices on over 120 bike retailers to guarantee that we find the lowest prices – to save you time and money.
It’s a promise we stand behind: If you find a lower price on a bike elsewhere, we will sell it to you for 10% less. For example, if you find a bike for $480 that we have listed at $500, we will offer you to buy it for $432 through BikeRide. The bike must be the same color and size, sold in the US and not include the use of a coupon.
If you find a lower price, email us at [email protected] with documentation of the price. We’re committed to making sure that the cost of a bike does not keep you from cycling!

Summary of Reviews
We have read all expert and user reviews on the HappyRun G300 Pro. In summary, this is what cyclists think.
7 reasons to buy
- Testers relish the throttle’s strong acceleration, instant response, and 50mph top speed.
- This bike comes with fenders, a 2,000 lumen headlight, and a taillight with brake activation and turn signals.
- A 200lb reviewer gets 34.5 miles of range using only the throttle over mixed terrain.
- In testing, the G300 Pro climbs steep inclines easily on throttle power alone.
- Experts say the adjustable full suspension provides a comfortable ride over bumpy pavement and dirt paths.
- The included 5A charger delivers relatively quick charging times.
- Reviewers compliment the authentic dirt bike look and eye-catching color options and decals.
8 reasons not to buy
- Experts find the brakes underpowered for the bike’s weight and speed, and the 180mm front rotor is undersized.
- At a tested 152lb, the G300 Pro is extremely heavy.
- Multiple testers describe the throttle as too punchy and sensitive, with abrupt power delivery that causes the bike to lurch forward.
- Assembly is more complicated than typical e-bikes, requiring installation of the rear suspension and front brake rotor.
- The listed height range is 5’1” to 6’5”, but a 5’5” tester says it's too big and a 6’4” rider finds it too small.
- The steep head angle makes for twitchy handling, according to a tester.
- Pedaling this bike is uncomfortable and impractical.
- Testers complain of rattling battery covers and creaky rear suspension.
Bottom line
At what point does an e-bike become an e-motorcycle? HappyRun's G300 Pro is a dirt bike with pedals attached to make it look like an e-bike, but the power and top speed aren't street-legal. The G300 Pro cruises at speeds up to 50mph and easily climbs steep inclines. The solid range, decent suspension, and quiet ride also impress. However, the high weight, weak brakes, rattling parts, and time-consuming assembly frustrate reviewers. Throttle power is also too aggressive for some. Nevertheless, experts think the G300 Pro offers good value for adventure junkies, but it isn't suited to wheelies or aggressive jumps.Expert Reviews
