A Weekend (or two) Project

This is what I've been working on the last two days of this GLORIOUS Canada Day Long Weekend.

Motor will be my current MXUS 3000W direct drive in 4T but if all goes well, I will slip in a 5000W model or a QS model.

Just finished 4 clamping mechanisms for my Norco City Glide.

Concept Picture, random pic off internet for brain storming idea's.

I originally was going to use Cyclone BB plate with clamps, but just went with all clamping plating action instead

Clamping action I used 5"L x 1"W x 1/4" plate and angle iron 2"x 3/16
Two cross beams on either side, I will get 5/16" thick 3/4" wide and 24" long.
The BB is a 68 x 110 or 113, old style. I am wondering if I should buy a normal BB and go 68x121/122/126 or a Cyclone 68x148 or 178.
As it stands right now, the original 68x110 or 113 clears the steel at the BB with the Cyclone crank freewheel.
Havent yet checked chainline from crank to cassette. Once I order the 68x126 it should suffice.


I tell ya, having only a DeWalt cordless went through 4 battery charges. Some drill bits were useless while others chipped away nicely. Angle Iron was easier. I thought because it was thinner, but its bc its HOT ROLLED STEEL. The Flat Bar was COLD ROLLED STEEL and the 1/4" took a lot longer to drill through. I priced out two pieces in 5/16 x 3/4 by 2' and hot rolled is $31.92 while cold is $42cdn. I will go hot rolled for the orange cross bar, if I need more strength I will cut 3/4" x 5" in cold rolled and weld it.

Everything is drive side flush with BB clamp.
One thing to note is the clamp by the BB is inline with the BB retainer on drive side.
The width of the clamps are 140mm to match the flats on the motor and of course the motor axle sticks out beyond that.
Rear wheel clamp is bolted through the kickstand bolt. Nothing else is bolted to the frame. Should I or not?

I re-read the whole post several times, but I can't find anywhere that says what the clamping stuff and bars are for.

There's a tiny part that implies they're for the MXUS hubmotor, which might imply they are for making a middrive with it...but it doesn't actually say.

So...what are they for? That might help us help you figure out if whatever you're doing with them will work....

Oh yea sorry. Will attach the clamp pictures I forgot to add.

There might be a problem with the 140mm width for motor flats down to BB, depending on the what bb spindle length I go.

Well, making a lot of assumptions from the pics since for some reason I can't understand you still haven't explained what you're doing or given details:


You're probably going to have to cut the MXUS axles off fairly close to the motor covers, probably too close for the nuts and other antirotation hardware to go on, or else it's going to be so wide you may have to ride bowlegged with your pants wrapped tightly to your legs with straps or something, to prevent catching them on the axle ends.

This means you'll need to build pinching dropouts to secure the axle.

This also means that whatever you're going to use to drive the chainrings from the motor will probably need to be pretty close to the motor cover itself.


More stuff later, gotta go to work.
