I'm adding an ebike system to my handcycle and finding that my left brake cable with wiring for the brake motor off circuit and the throttle are putting a lot of weight on the brake cable and it doesn't stand up as well as it used to. There's no room on my right hand pedal to mount the throttle.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7560972471987417247.post-34893222548275361042012-02-17T20:42:03.273-05:002012-02-17T20:42:03.273-05:00BTW, I found a 118mm bottom bracket axle -- 11mm w...BTW, I found a 118mm bottom bracket axle -- 11mm wider than my existing axle. The chain is not clacking against the carbon fiber fork nearly as much (see picture above where white tape covers the area where chain was hitting),Bruce Chasehttps://www.blogger.com/profile/12547917183274805275noreply@blogger.comtag:blogger.com,1999:blog-7560972471987417247.post-10837515770276600332012-02-17T20:38:50.354-05:002012-02-17T20:38:50.354-05:00You are so right.

I looked into Arduino, Gageteer, and other toolkits with bluetooth interfaces for which I might be able to program the controller to work with motors with proper gearing to power gear shifting. Downshifting takes little power. Downshifting (on the I-Motion 9 speed hub), appears to happen by merely releasing more cable. I suspect that the hub moves to first-gear on a broken cable.<br /><br />I would probably keep the motors and gears on the inside of the main portion of the fork (you can see in the pictures above that there is a lot of room there) and run a cable to the hub. The reason for this is that I can build a carbon fiber holder/support for it within the fork; the controller can be larger than a store-bought one; the contraption may take a few motors for which I would have plenty of room; and the battery can be protected.<br /><br />My next project... if this works.<br /><br />GranFondo... I hope my "training wheels" work. I can already see myself going up those 2 mile/20% grades with my odometer reading 0 mph -- albeit, I would still be moving. If this works, I will be going over 50mph downhill though.Bruce Chasehttps://www.blogger.com/profile/12547917183274805275noreply@blogger.comtag:blogger.com,1999:blog-7560972471987417247.post-22521175788685774462012-02-17T17:39:19.804-05:002012-02-17T17:39:19.804-05:00interesting problem - seems tailor made for electr...interesting problem - seems tailor made for electronic shifting so as to avoid the entire cable problem altogether with an electric brush on the crank and a Di2/EPS equivalent for a hug gear. this is one cool looking bike - can't wait to see you at granfondo!christophhttps://www.blogger.com/profile/05858722838025059826noreply@blogger.com
