I have been commuting to work on this bike all year. It has been very reliable. I still charge it at home and work (unless I forget to charge at work), so the 12S LiPo pack never goes over 49V and never goes under 40V. This should maximize the number of cycles that the batteries will deliver. There are a couple places I need to crank up the speed to 40 MPH or so for merging in traffic, but otherwise I try to keep it to a pedestrian 30 MPH.
The RC CA has been working well, except for the surge bug. I was hoping somebody in the US of A would get the $50 dooda to update the ROM to the version without this bug but it looks like I will need to get one myself. The biggest difference I have noticed, is the low RPM response. With the old RC servo tester I would have to pedal up to 5 or 10 MPH before applying power to avoid motor stuttering. Now I can just pedal one stroke and start applying power without any stuttering.
I bring the bike up to the computer room in the freight elevator for charging (and to keep it safe) every day at work. Today one of the largeladies in the elevator commented that it was quite the contraption.
I like to improve things constantly but I am hard pressed to think of a way to improve this contraption.
Ok, here are some:
* Replace rear cheesy spring shock with air shock for better handling (have air shock - just do it)
* Make it lighter (60 lb currently, can probably shave 5 lb off of rear swing arm by building a new one. Probably not worthwhile?)
* Change 20" tires to wide rims with Pirelli scooter tires (I have had no flats - is there any other reason to do this other than because is cool?)
I still have the 3210 motor that I converted to sensored with the Lyen controller that I should build up a bike with but I have not yet been struck with inspiration. Maybe I need to buy a trike just to add a motor...
