48V 20Ah/13.5Ah Samsung Lithium-Ion Battery
The ZM model is fitted with the best of all Samsung’s new battery models, offering you two options based upon the battery capacity - the 48V 20 Ah and the 48V 13.5Ah. The introduction of such technology and capacity to the battery pack extends not only the range of your ebike on a single charge but also the service life. The battery of 20Ah allows you to travel around 60-80 miles on a single charge, while the battery of 13.5 Ah has a range of 35-50 miles. Meanwhile, if required, you can recharge any of your electric devices through the USB port on the battery.

Hydraulic Disc Brakes
To match up with the ZM -one of the most powerful electric bicycles, we’ve used a combined braking system, which allows the front and rear disc hydraulic brake to actuate and work together seamlessly, providing great braking power. Beyond that, we integrate the motor cutoff capability into the brakes for extra safety.

Q: Will the G-FORCE ZM be a good fit for me?

The recommended rider height for this model is 5'5" or higher. The best way to know whether it works for you is to take your inseam measurement (inside leg length) and bring the seat height into the reference scope. On the other hand, the ZM model can bear up to 400 lbs (the maximum weight load capacity) so it is not recommended for a rider to go over that weight limit.

Q: Will it be difficult to assemble the ZM myself?

The ZM arrives 85% pre-assembled and allows you to get the new bike assembled in a few simple steps after delivery. You'll find specific video that explains how to properly assemble your bike. Basically, it does not require special skills or much professional knowledge so self-assembly at home won’t be a problem even for beginners.

Q: What are the differences between the ZM - 48V 13.5Ah model and the ZM - 48V 20Ah model?

The differences are in the pricing, range, and charger that comes with the bike. The larger of the 2 battery options has a 3A charger (more current capacity) to reduce battery charging time; in the meantime, it delivers a longer riding range under the same operating conditions. The 20Ah battery pack will get you more range up to 60~80 miles on a single full charge.

Q: Can I add a second battery to the bike?

Sure, you can purchase spare battery pack from us if needed.

Q: Can I adjust the handlebar height?

No, the handlebar on this model can NOT be raised or lowered but will give you some adjustment in handlebar angle.
