G-FORCE ZM Electric Bike Review: 1300W Electric Moped Cruise!

The G-FORCE ZM electric bike is one of these electric bikes which borrows a lot from the motorcycle style while maintaining its legal e-bike status. But the influence of the motorcycle is not only profound; it also has a powerful ride to match.

Rides like a small electric motorcycle

Everything about the G-FORCE ZM screams motorcycle, not bike.

I would call it a fairly true-to-form e-moped, even though it technically fits into the e-bike classification.

Yes, it’s a Class 3 e-bike in the US, but it’s more like a moped that has vestigial pedals to rest your feet on. You can pedal with a dead battery, but the 85-pound (38 kg) bike won’t be a pleasure to pedal more than around 4-5 mph (8 km/h). And lord, help yourself if there’s even a little uphill on your pedal ride home.

But with the option for a 48V, 20Ah battery (or a smaller 13Ah battery if you want to save some cash) you should have plenty of range for a day trip. And since the Entry-level model at $1,899 with the 13Ah battery is only $100 cheaper than the 20Ah version, I don’t know why anyone would want to spend that extra Benjamin to get 50% more range.

As well as a decent range, the G-FORCE ZM is also fast and peppy with a top speed of 45 km/h. The 750W Bafang motor actually produces closer to 1,300 watts of peak power, and the bike has good acceleration under my 150-pound (68 kg) load.

The dual-suspension setup makes for a comfortable ride, though I’m not sure how the suspension would fare under the 400-pound (181 kg) maximum weight (or if the acceleration would be nearly as peppy).

The 110mm-travel suspension fork is adjustable, but the rear suspension is kind of a what you see is what you get situation. It’s fine for me and a good ride, but it’s not exactly going to handle a downhill mountain bike trail. The speed bumps are a bit more his pace.

Which also begs the question, why did they give the bike knobby tires? The fat 4″ tires in 20″ diameter are fine for street riding, except the knobbies don’t give as much traction as I would like on asphalt. You could theoretically do some off-roading with these tires, but the suspension isn’t really designed for anything more than a shortcut over fairly well-maintained grassy terrain. I would have preferred to see road tires rather than off-road tires, but tires can of course be swapped at home or by your local bike shop.

I really like the tires that Specialized shows off on its budget utility bike, which feature a street-optimized center patch with edge knobs for better off-road turning. It would have been a good compromise here.

Another upgrade I would have liked to see on the G-FORCE ZM would have been larger disc rotors. Hydraulic disc brakes seem fine, but the smaller 160mm rotors will definitely heat up quicker when repeatedly stopping this heavy bike at higher speeds. It seems to me that 180mm rotors would have been a better choice.

The G-FORCE ZM still scores several points in my book, although I would have liked to see brake and tire upgrades.

The bright and colorful LCD screen is easy to read at a glance and looks much better than the screens we often see on similarly priced e-bikes.

The motorcycle tank-shaped battery is a cool feature that adds to the fun vibe of the bike, although I can already guarantee there will be some armchair physicists in my comments section below to educate us. on the travesty of having that weight higher on the frame. In practice, the rider’s center of mass, which is around 15 times heavier than the battery and much higher, is going to have a much greater effect on the handling of the bike. And for a bike that’s going to spend most of its time riding straight down a bike path or making 90-degree turns on city streets, that tank battery’s higher center of mass just won’t. very noticeable. So for me, I’ll appreciate the fun motorcycle-style design.

It is true that a lower mounted battery would be technically better. But after cycling and also riding others with weaker batteriesI can tell you that the difference is just quite small, all things considered.

There are other great features that are often overlooked on these moped-style e-bikes, such as a 7-speed Shimano drivetrain and a USB charger built into the handlebar display. The massive LED headlight and included LED taillight make the bike highly visible, which is important for commuter-style night riding.

While I might nitpick over the G-FORCE ZM’s smaller brake rotors and tire choice that doesn’t quite make sense, there’s a lot more here that I like than I don’t. not.

The full-suspension setup normally drives the price quite high, but a starting cost of only $1,899 feels reasonable for a class 3 e-bike with dual suspension, hydraulic brakes and a few nice extra features.

A pair of footpegs is pretty much all that’s missing to make this a pretty impressive urban cruiser, giving motorcycle vibes in an e-bike price range.

It may not have the gravity of a SUPER73 or other big name moped-style e-bikes, but it certainly offers a fun and reasonably priced ride!
