Motor and cabinet for Shimano E8000 series STEPS system


A cabinet is now possible to buy from frambuildersupply.com, any chance the motor and cabinet could be introduced as a model element in BikeCad?

Thanks /Jesper, Sweden

Thanks for bringing this to my attention. I've just e-mailed Framebuildersupply.com to request a drawing for this part.

Motor Cabinet Bafang MAX drive M400

Bafang also offers a motor cabinet for their M400 for sale for hobby builders.
Google let me find this cabinet only in a dutch webshop.
But I cannot imagine it is not available worldwide


Shimano E8000 series STEPS system

Thanks to Framebuildersupply.com for getting me the CAD data for their Shimano E8000 series STEPS system motor cabinet. This cabinet will be available in BikeCAD version 14.

Would you provide me a e8000's step file?

I am doing retrofit my ebike with e8000 motor but it is difficult to fit to my new ebike frame without proper dimensions.


... I just use Catia...

I regret that I do not have the E8000 motor as a STEP file.

Great, thanks!


Since we're talking about ebikes.

Could you allow batteries to be mocked up on the ST as well as the DT? 

Battery mount

When the e6000 series motor was first added, I included the option to position the battery on the down tube as well as a different style of battery that was meant to be rack mounted. Although I now have the e8000 series motor ready for BikeCAD version 14, I don't actually have a model of the new battery, so for now I'll just have the e6000 series rack and downtube batteries paired with the e8000 motor.

The Bosch motor available in version 14 will also feature a downtube mounted battery. I had not considered the possibility that one might want to mount it on the seat tube. If others are also interested in this, I'd be curious to know.


I hadn't considered it either

I hadn't considered it either until it was requested by a client. The BMC Alpenchallenge (https://amp.bmc-switzerland.com/e-bikes/lifestyle/alpenchallenge-amp-cit...) has this -- I'd be that's where the request comes from.

Seat tube mounted battery

I've just set things up so both the Bosch and Shimano batteries can be mounted on the seat tube. Here's a screen capture from the next update of BikeCAD.

Thanks so much!

Thanks so much!

Stoker Motor Placement?

Is it possible to postion the motor cabinet and battery on the stoker BB for a tandem?  I'd like to be able to add a second battery and try out various locations with in the stoker area of the bike.

E-Bike motor at the stoker BB

Although it is currently not possible to add an e-Bike motor at the stoker BB, I've just added this option to the next update of BikeCAD.

Position of e-Bike motor

Hi Brent,

Can you allow the position of the motor to either BB's and also the Boom Tube in variable positons please.  When is the update due for this?



Position of e-Bike motor

Yes, you will be able to put a motor at any BB location. You can even have multiple motors if you like. I'm not sure what you mean by the boom tube in variable positions.

That sounds great!  Do  you

That sounds great!  Do  you know when the update will be released?

I hope to have it ready for NAHBS by the end of the month.
