Foreword: This first post maybe tweaked over time, to keep any updates in one spot, or fix any errors.
For sale is the next 'Beta' batch of my Commuter Booster drive units.
This is a light weight friction drive ebike system.
See the website for more details. http://sites.google.com/site/commuterbooster/
Or the development thread on ES here. viewtopic.php?f=28&t=22187Price is AU$170 + shipping.
Shipping was in the AU$20-25 range last time, so should be similar but I will update this post when I get real quotes. Let me know if you would prefer registered post, or cheapest option. My preference would be registered just in case.
Note: This is for the mechanical components only. You will still need to provide you own battery, motor, ESC, and throttle solution.[EDIT: 2011-12-17
] Here is a link to the complete shopping list
I can provide the motor and ESC if you wish, but will charge a mark up to cover my cost of ordering from HobbyKing or Leader Hobby, assembling the drives, setting up the ESC, extra shipping costs etc.
The design is only slightly different from the Alpha units, the key differences being:
a) a press fit for the main pivot shaft into the swing arm (an Alpha tester wanting upgraded parts let me know)
b) removed face exit phase wire slot (not shown in photo)
c) added mounting holes for 44PCD & 30PCD mounting holes to suit most 63 & 50mm motors (not shown in photo)
d) added a hole for securing phase wires to swing arm
e) fully assembled, minus the motor
Here is what a complete system looks like on the bike. This whole bike weighs in at ~14.5kg total, including the drive unit, motor, ESC, BrainBox interface and a 5s20Ah battery pack. This can peak over 2000w, but I typically run it at 500-1000w power limits.
To place an order send an email to email@example.com
(or a PM but I prefer an email). With the following details.
- Seat tube diameter (check the installation template
to ensure it will fit your bike)[EDIT: 2011-12-17
] I still have some smaller swing arms suitable for 50mm motors. So if you are happy with lower ~500w power limits, this may be for you.
- Quantity required for each seat tube size
- Any special instructions
I have just placed orders with my suppliers for the updated parts, so these are not likely to ship prior to Xmas. Sorry, I'll try my best.I also have my Brain Box for sale in a seperate thread
. The Brain Box is my custom design ebike computer/throttle interface/data logger specifically tuned for the Commuter Booster friction drive. I highly recommend it as it makes the whole Commuter Booster a refined and integrated package, and is the whole reason I delayed releasing the Beta units so I could sell people both. I'll leave the details for the other thread.
I'll be updating the Commuter Booster website
soon to reflect all the latest developements.
Also check out the videos on the Commuter Booster Youtube stream
which shows all the steps off putting a complete system together.
Here is the one showing the assembly of a motor, onto the Commuter Booster unit.
