You may choose this for your own reasons, but I suggest an alternative. There are many good reasons to design our towns and cities so that walking and other short travel suffices. For use in the distorted cities we have (and between them) high speeds may be useful, but living this way...

I edited my post.

Mixed riding, hills and flat, motor stops supplying power above 25km/hr - around 7.7 Wh/km for the Greenspeed Magnum Big Wheel trike in the signature, with a Shengyi SX2 fast-wind mounted as a mid-drive with a 26T sprocket on the motor driving a 48T sprocket on the rear wheel. Per Australian...

What's chasing me?

You can get mag wheels for it: https://www.worksmancycles.com/media/2014/upgradeguides/Adaptable.pdf

You've possibly already found this, but have you asked them for details, or how to remove the tire, etc? Worksman Adaptable Industrial Tricycle ADC-CB

Putting the controls through a screen means it can be hacked. Can we build such a system that is more difficult to hack? Or course, but so what? Manufacturers will not do that - it's not something they are rewarded for doing (or punished for not doing - yet). The control system must be...

There is an element of 'magical thinking' in this, in the sense that you look at the part and think that it is homogeneous, evenly and perfectly composed, and also that your own changes are the same. It probably isn't - it's just as likely to have unresolved stresses and unevenly mixed...

Power from an electric motor is partly a function of speed (=torque x rpm). I want power to get heavy loads up hill. Safety can be addressed by mandated speed limiters - power is not relevant. Illegal changes to controllers are exactly that - illegal. I've read another post recently about (I...

Hey AW, my understanding is power delivery permits a speed - that is, if the motor doesn't dole out the power needed to match a given friction+air resistance+geometric gravity input I won't maintain that speed. But torque permits an acceleration. Or not.

Speaking of non-sequiters, my mind persists in attempting to envision AW racing on his trike in this accessorized with n+1 enormous dogs. I would probably get out of the way.

EVs are booming but electric bikes are really cutting emissions

My point is that the existing design makes choices for you. That chain must clear the tire in any chainline it may assume. The range of chainlines that result from a cassette or freewheel dictate a distance the front sprocket must exceed to prevent the chain from rubbing on the tire. A single...

Well, what does the bike have now? At least that might fit.

My security is a 'Sold Secure Diamond' U-lock and a cable to reach the front wheels to slow them down, but I'd like opinions on an idea. I've identified a switch into the controller on my trike which sets the motor to reverse. I am working out a switch and location - my idea is I can reach the...
