Features and Overview of the Gotway MSX
Gotway MSX Background

Gotway MSX Background:
The MSX is now the fourth iteration of  Gotway’s 18″ Electric Unicycle over as many years. In the earlier 2017 model, the V3S+, was the first 84V high performance Wheel with a maximum cruising speed potential of upwards of 30MPH, a 1600Wh battery pack to provide in excess of 60 miles range, & an integrated handle. Despite being one of the highest performing Electric Unicycles then made, the first units to roll out of the factory were not without some serious design flaws, such as a control-board with a statistically high failure rate, & wiring that had a tendency to overheat. These flaws were mostly worked out quite early on in the production cycle, but the issue of the controller reliability was never truly mastered, particularly when compared to other models from the competition. The MSX set out to address the deficiencies of the early generation, one that would stand up to the test of time.

What’s New on the MSX

Gotway MSX Improvements, Larger Tire

Tire Size: Unique to the MSX, is its 19″ x 3″ tire, vs the 18″ x 2.5″ on the MSuper V3S+. The larger tire, especially the width, makes it more capable of traversing through different terrain medium like soft dirt, gravel, while providing a smoother, more comfortable ride. There is an increasing trend among manufacturers to fit use wider tires. At the extreme end of the spectrum, is the Ninebot Z10, with it’s spectacularly wide 4.1″ tire.

Gotway MSX Improvements, Higher Pedals

Pedal Height: not only is the tire 1″ larger in diameter than the previous model, but the pedal height has been increased from 5.11″/13cm to 6.5″/16.5cm. Higher pedals provide more ground clearance for ground obstacles. This also changes the dynamics of the ride, altering the center of gravity. On the plus side Customers report that it feels more stable & secure, but there is a trade-off in responsiveness & acceleration.    

Gotway MSX Improvements, TO-247

Completely New Controller Design: the most significant changes on the MSX are to be found under-the-hood, on the controller, which has has an entirely new architecture. The MOSFETs—the solid-state components that drive the motor—are using a new state of the art chop which has a theoretical max burst specification of 1000A, & up 300A for a short sustained duration. The TO-247 MOSFET package has a superior heat dissipation properties, also the heat-sinks are applied over a larger surface area for superior cooling. The result is a controller that can now provide twice the amount of sustained power over the previous type.     

Gotway MSX Improvements, Spring Connectors

Low Resistance Board Connectors: with such high currents, the motor wires & connectors must be up to the job of supporting them. On the V3S+, these motor wires were soldered directly onto the board, connected to the motor with a EC5 banana connectors. The main disadvantage of these, was that it was time-consuming & troublesome to change an innertube, where the heat-shrink insulation had to be cut opened & new ones fitted. Now the connectors are screwed directly into the board, easing routine maintenance work, while also introducing less resistance in the connector interface.
