Jason McNeil Posted July 12, 2015 Share Posted July 12, 2015 Without any revolution developments what would you like to see in the perfect eWheel. Here are some thoughts:16" wheel: in my books, this gives you the best compromise between maneuverability in an urban setting & ride comfort64 cells in the battery: it's a bit of an anomaly that while there are several 14" Wheel with 64 cells, only Firewheel has a 64 cell 16" wheel. On paper, 64 cells, >520Wh looks like complete overkill, I haven't seen many reports of people regularly travelling more than 40km on their eWheel; on closer inspection the advantages of this enormous energy reserve are: 1) there is increased safety margin to deliver power, significantly reducing power cut-outs in situations like extreme acceleration, 2) because the load is shared across all the cells, in theory this should extend the life of pack, 3) there will be fewer situations where the pack is completely drained, further extending battery pack life, 4) can sustain continuous long hill climbs (less voltage drop).Clip-on side-panels for easy battery removal: if each of the four parallel packs could be optionally connected/disconnected without resorting to tools & taking less than 30 seconds, you could travel on flights taking along a single, or perhaps two, battery packs without much fuss. Weight: under 12kgs. If manufacturers can find a way to produce a motor/wheel/tire that weighs <7.5kg, this should be achievable—again, nothing revolutionary, just ~1.5kg shedding of weight from existing motor design, I'm reliably informed this is well within the realm of possibility. Remaining weight is: 3kg for the battery pack & 1.5kg the shell, control-board, wires ,etc.Fast-charging & smart-charging: there's a couple existing eWheels that could possibly be candidates for fast-charging. When Ninebot released the specifications of their 9B1 last year, a fast-charger was prominently listed as an optional accessory. Now more than eight-months later, there is still no sign of this. There is no technical reason why, especially higher-capacity eWheels, charging time could not be reduced to under 1.5 hrs. In combination with fast-charging, the option to limit charging to 80% would not only reduce the charge time to under 1hr, but potentially double the life-span of the battery pack as well! Intelligent LCD Data Panel: integrating a power meter that could also display speed, trip odometer, Wh remaining, & historical power graph. The phone app is all very well, but I think it would be great to have this info displayed right on the eWheel.High construction quality: properly water resistant, good quality plastic (or other material) shell, a gauge wiring that can support currents much higher than 'normal' conditions.BT Adjustable Pedal-tilt-back Speed: at which to set the maximum 15° tilt-back speed. For maximum safety, maybe a set number of km that needs to accumulated to attain a faster level (apparently the Inmotion app has a similar feature)TAdded 14 Jul, 15:Gradient LED Power Availability: the concept here is for a fairly bright LED ,which would be be in peripheral field in vision, to represent the available power (0-100%) by transitioning from Green-to-Red. For example, if you're riding along up a hill at 50% available power, then it colour would show as orange, beyond 75% & the brightness intensity increases & the hue is a vivid red.
