3rd Generation of the Gotway ACM
Q: What are the main features & specifications of the ACMv2 Compared to other high-performance Electric Unicycles
Q: Beside the battery size, are there other differences between the 1,300Wh/1600Wh Wheels?
A: Both the 1300Wh & 1600Wh are identical in terms of power output & top speed: the 1300Wh pack contains 120x of the 2.9Ah Panasonic NCR18650PF cells, while the 1600Wh pack has the same number of cells but with the higher capacity 3.5Ah Sanyo NCR18650GA type.
The actually capacity of the pack is slightly lower than what Gotway advertises, as is illustrated below:
- 1300Wh Panasonic NCR18650PF pack: 2.9Ah (rated capacity) x 3.6V (nominal voltage) x 120 cells = 1252.8Wh
- 1600Wh Sanyo NCR18650GA pack: 3.5Ah (rated capacity) x 3.6V (nominal voltage) x 120 cells = 1512Wh
Earlier versions the ACM operated at a lower voltage voltage of 67.2v, which limited the potential maximum speed of the Wheel to under 25MPH. With the introduction of the ACMS+, the voltage has been raised to 84.2v. This voltage allows for a higher cruising speed by providing a larger buffer against ‘brown-outs’. This is where the voltage required, usually during demanding situations like climbing a steep hill or mountain, exceeds the available voltage of the battery pack.
Q: What are some of the benefits of the ACMv2 compared to either MSuper or Monster?
A: The ACM is considerably lighter than either a MSuper or Monster. In the 1,300Wh/1600Wh configuration, the weight of the v2 is 46lbs, the MSuper rolls in at 50lbs, & the Monster weighs in at a hefty 72lbs. The lower weight & smaller Wheel size allows it to feel more maneuverable & nimble.
Pricing is favourable in the case of ACMv2: for the 1300Wh battery pack version, it’s just $1,290, & $1,587 for the larger 1600Wh pack.
Q: How will the higher cruising effect range
A: Quite significantly. Beyond 30kph/18.6mph most of the expended energy is spent overcoming aerodynamic drag.
Q: What is a ‘Safe’ cruising speed of the Wheel?
A: Electric motors have an optimum operating window; beyond a certain speed/rpm, at a given voltage, the torque output of the motor will drop away reducing it’s ability to effectively balance. While Gotway may have a specification of speeds in excess of 30MPH for the Tesla & ACMv2, it is highly recommended to not push the boundaries beyond this—there has been one report of Tesla of a cut-out at 34MPH—you must have plenty of margin between the speed that you ride at, & the cut-out threshold of the Wheel. To preserve you skin, at the very least, the Rider is strongly advised to wear wrist-guards, knee/elbow padding & a helmet, the risk of major injury goes up exponentially with velocity.

It’s also important to exercise restraint & due-care when using this powerful class of vehicle, opening up the throttle ONLY when it is appropriate & safe to do so.
Q: Is it possible to upgrade an existing ACMs+ to a V2?
Perhaps this will be a possibility in the future, but at the present we do not have sufficient quantity of spare parts to offer this as an option. Beyond the control-board & motor, the ACMv2 also has a brighter headlight for operating in the dark.
Q: Do you stock spare parts for ACMv2?
Yes, we will have a full complement of all the spare parts needed to totally reconstruct the Wheel, if necessary, these are will be available for purchase from shop page.
Features of the 5A Rapid Charger:
When purchasing a Wheel, for a $100 supplement, you have to option to acquire the latest eWheels branded 5A charger.
From the standpoint of charging time, this will allow you to charge the Wheel at a faster rate than is consumed while riding at moderate cruising speed—at 20MPH, the Wheel uses around 350W of power, while the maximum output of this charger is 420W.
The other significant feature of this charger, is the ability to partially charge the battery to either 80% or 90% of capacity, potentially extending the lifespan by up to 4 times the normal 500 cycle count, to over 2,000! This is because destructive chemical reactions inside the cell are most active at the higher charge state. The same technique is used by electric car companies, like Tesla, to maximize the potential useful lifespan of the battery pack.
