Summary of Reviews
We have read all expert and user reviews on the G-FORCE ZM. In summary, this is what cyclists think.
10 reasons to buy
- An expert calls the ZM "fast and peppy" with a "decent" range.
- Reviewers agree the ZM is reasonably priced and a good budget-friendly alternative to similar Super73 models.
- This bike can carry two people thanks to the 22-inch-long seat and 400lb load capacity.
- The max speed is easily adjusted to fit Class 2 or 3 restrictions via the display.
- An expert says the display is colorful, easy to read, and much nicer than those typical of competitors. It also has a USB charge port.
- The ZM has front and rear LED lights. A reviewer says the headlight is "fantastic."
- Experts agree the ZM has a distinctive, attention-grabbing style. They also appreciate the battery design, styled like a motorcycle fuel tank.
- One tester notes the simple motor cable disconnect, which makes tire and tube changes easier.
- The Ronglun hydraulic disc brakes are powerful and effective, according to reviewers.
- Experts say the suspension, fat tires, and padded seat provide a comfortable on-road ride.
12 reasons not to buy
- The misleading "14-day free returns" policy is a minefield of conditions. There's a 25% restocking charge, return shipping isn't included, and the box mustn't be opened.
- Buyers voice frustrations over poor reliability and non-existent customer support.
- One tester finds quality-control problems that could result in damage during assembly. Another's ZM is missing a fender.
- The cramped riding position and ghost pedaling at high speeds mean pedaling is uncomfortable and impractical. A realistic throttle-only range is 30 to 40 miles.
- Experts lament the lack of rear foot pegs for a passenger.
- At 92.5 pounds as tested (G-FORCE claims 85 pounds), the ZM is heavy, even for a motorcycle-style e-bike.
- A tester says the bike is sluggish when pulling away and when starting to climb. A user complains of his ZM's lack of torque.
- The rear light doesn't operate as a brake light.
- Experts agree that the suspension isn't suitable for off-roading. One thus questions the purpose of knobbly tires instead of slick street tires.
- The ZM's 160mm brake rotors are too small, given the high weight and max speed.
- According to one reviewer, motor assistance is too weak in PAS 1 and too strong at higher PAS levels.
- The display menu settings are confusing and hard to use.
Bottom line
The G-FORCE ZM is a motorcycle-style e-bike with a 750W motor, 960Wh battery, and fat tires. Experts agree it's fun to ride and comfortable on the road. However, the primitive suspension limits off-road utility, and there's no practical way to carry cargo. The ZM is also very heavy, even for this style of e-bike. Although it looks like a decent option for riders seeking a license-free alternative to a real motorcycle, the ZM (and G-FORCE generally) appears to suffer from quality-control issues and poor customer support.
