Frequently Asked Questions
- Although EB has demonstrated a ‘no-load’ speed of 200kph/125MPH, what is the actual ride potential of this Wheel?
This remains to be seen. The general safety margin between ‘no-load’ & ‘cruising speed’ is about 15-20kph/9.3-12.4mph; however, the GT PRO has a 75kph speed delta of CommanderPro 50S & LK Lynx, no one has, yet, tested riding at anywhere near this speed, which is equivalent of facing the full fury of a category 3 hurricane head-on! - Will the GT PRO be offered with different battery packs?
Packaging a 168V/40s battery pack presents some unique challenges in a Wheel, this constrains the maximum capacity to 4x parallel circuits; it’s unlikely we’ll see a 6p version of the GT PRO, without resulting in an unwieldy behemoth. To power the machine, the high-power Samsung ~30A 50S cells are required. Begode is not planning on producing a 50E version of the Wheel. - When will the first shipments GT PRO take place?
First production is expected to take place in mid-late February. - What fault-tolerance measures have been considered in the design?
At the battery pack level, these are independent, up to two packs can fail & sustain a fairly high load. While under rotation, the controller ignores hal data, in the event of failure & by packing in so many MOSFETs in the controller, reduces the stresses on any given chip. - How much of the 100mm of suspension travel is functional?Â
Unlike the linkage system employed on a number of other Begode models, one of the key benefits of the vertical suspension module is that it offers the full 100mm of travel vs 60-70% of the claimed travel range. - What charger is packaged with the GT PRO & what is the maximum rate of charge?
Another first for the GT PRO is the inclusion of a 10A/168V charger, capable of charging from 0-80% in under 1.5hrs. The maximum rate of charge is 20A/3,360W, assuming a 25mph cruise speed, this is of a 4:1 ratio of ride-to-charge time.
- Does the GT PRO have different ride heights?
This is a first for Begode/EB, the adjustable pedals brackets; the height can be changed from 230, 240, 250mm/9, 9.45, 9.85″ inches for different ride preferences & situations. The Wheel will be fitted with the CNC pedal kit as on recent Begode/EB models. - What tire is the GT Pro installed with?
A new (for a Wheel) Maxxis slick ‘semi-hot’ 21″ 100/90-14. This is a high performance motorcycle tire, more details will follow. We are working to try to be have the tire installed in a tubeless configuration, for reduced maintenance & downtime. - Will the CNC front/rear roll-bar & handle be included as standard equipment?
Yes, those parts will be included as part of the shipped package. - Are Velcro pads included?
Yes, same style/type of pad as the other Extreme Bull models, such as the Mini, CommanderPro, & CP 50S. - Are the CommanderPro & recent CommanderPro 50S still relevant?
Yes, while the GT PRO dethrones other contenders for the title of the ‘Highest Performing Wheel’, it does not come without sacrifices: the battery capacity & expected range in like-for-like usage will be at least 20% less than the CP & CP 50S; the weight is considerably more & from the first appearance it does not win any beauty contests. - Were there any unique changes made to the motor for the higher rotational speed?
According to Begode, yes, they’ve collaborated with the motor manufacturer for this release, beyond just throwing a larger voltage into the windings. but they’re reluctant to share the details of the internals (for now)… The permanent magnet/stator width is the same 38mm as on previous iterations of the Master, MasterPro, CP, CP 50s.
