Street tracker build

Post by Toby82 » Aug 29 2017 6:26am

About two years from when the idea of building an electric flat tracker style street bike first started to now and I finally having a rolling bike to show.
Frame and swingarm has been designed from ground up and will suit either an Emrax 228 or zero 75-7 motor and around 5 kWh of lipo.

It's looking great Toby! Love the use of the battery box as a structural element!

Cool! I just made another 550 cell order, but half of them are spoken for. I should have about 240 left. Might be a bit short of what you need but we can always order more.

That thing looks awesome!
I'm in Newy too. I'd love to see it going one day.
Where abouts in Newcastle are you?

Dean

I'm down in Valentine on lake Macquarie.

Hopefully bike will progress quite alot between now and Christmas. I'm currently held up awaiting parts.

Cheers Toby

Cool.

I'm in Swansea. I'd love to have a look at it some time. I gotta finish my electric minibike too.

Quick update.

2017 75-7R motor coupled with a Sevcon Gen 4.5 size 6 has been ordered and should arrive mid to late Nov. :D

Nice nice! That motor should be good for peaks of 50 kW right?

This drive train setup is what Zero is running in the 2017 SR. Zero states 52kw peak and 775 amp. I'll start with a 5.4:1 gear ratio so should get decent acceleration with around 850nm delivered to the rear wheel...

Nice build. Clever use of the battery box as part of the frame. This thing will fly with the new motor and controller combo.

Update after some slow progression on my bike build.
Motor is now mounted and battery box mock up complete.
A little more fabrication work and it will be ready for battery.

Coming along nicely. Man there are some really great builds going on now here on ES.
Keep up the great work. Look forward to see videos of the completed build.

What about air flow for the motor shell? Are you pulling air from the front of the battery box?

Looking good! That motor should move a bike of that mass pretty nicely.
Sing out when you're ready for batteries.

Cheers mate. Current design has Air flow channeled from underside of battery box up along front side of motor.

I'll dig out some more pics of frame build and CNC work over coming week.

Thanks mate. I have been considering using 18650 (25r) cells in a 28s24p layout but I'll throw you an email to discuss.
