Specs

[Hoss]

Before purchasing a Q-45 for long-distance travel, some compatibility issues need addressing. The plan is to electrify the rear-wheel and belt-drive the front. Upon investigating the rear-motor issue, was unable to find the thru-axle diameter and length? Fork width wasn't clear either? Motor requires a torque-arm and it isn't clear from the specs how that might be accomplished? There also remains some questions about brake-rotor diameter and clearances once a motor is installed? The motors have spoke options, number of spokes and wheel-lacing options. Couldn't find those specs either?

Haven't gotten to the belt-drive questions yet, but upon glancing at specs, those seem a little thin/murky as well.

Perhaps, detailed specs are on some different web-page that isn't linked on the Q-45's page? Thanks in advance.

Hub widths are standard 100mm (front hub width) for our rear wheel, 142mm rear hub width for the drive wheel. Through axles are 12mm - our axle for the front fork is longer than a standard through axle though because of the need to pass through the stays - but in any conversion you would be using our axle anyway...

For a belt - not sure how you will tension it as there are no adjustable dropouts so likely only an eccentric BB will work and those really aren't super reliable in my experience. The frame is not technically designed with belt use in mind. For example - to use a Gates belt as OEM the frame design has to be approved by Gates and have a slew of special features and allow for a large amount of tension to be applied to the belt.

Finding a 100mm through axle front e-hub is a real unicorn - but there are a few I have heard rumors of... but I have not seen one other than drawings at the main bike shows. Front through axle e-hubs just aren't on the regular bike market radar.

For spokes - I imagine most e-hubs will be 32 spoke at minimum or more and could possibly be related onto our rims, but getting an entire new wheel set is usually cheaper than paying labor to replace wheels which is a real headache anyway.
