Foot

June 30, 2010


So I’ve broken my foot. I’m not good at being unwell, I moan alot and tend to limp around the house with a pained expression while of course attracting little sympathy from the family (not true really my 7yo boy has been very caring really).

No I didn’t come off my bike, no it wasn’t that dangerous downhill skateboarding thing I sometimes do. I was switching off a light and just took a bad step…such is life.

With the greenewheels bike I’ve not mounted the battery in the original location yet, although I’m pretty sure I’ll be able to, I’ve got it sitting in a rear basket to test the whole thing before I go to the trouble of making a more permanent solution.

The Ping battery will physically just fit in the space where the original was so in order to make a casing for it out of plywood I need to be millimetre perfect in it’s construction or it will foul either the rear wheel or the cranks. My first attempt at cutting out the wood just didn’t fit so I’ll have another go making the box a little bigger and slowly reduce it’s size until it fits perfectly.

So I’ve got the Greenewheels going with it’s new battery and even with a broken foot it is the best way to get to work as I can ride right up to the front door (it’s walking that is difficult!).

The handlebar change and front disc fitting was very easy really and the brakes are great, strong reliable (no shudder!) and work well even with the pretty average original electric cutout brake levers. The bike is again pretty much the same as it was when I was riding it last year but I have disconnected the primitive pedal sensor setup. It took too long to come on, too long to turn off again and added too much power when I didn’t want or need it.

I have really been able to appreciate this lighter and faster ebike this week or so. I’m convinced the new controller makes the bike much torquer but it’s been a while since I rode it in original configuration so it’s hard to remember. Top speed without pedaling feels basically the same (28-29ks) but I’ll need a speedo before I can be definitive.

Riding this style of bike with the whisper quiet hub motor makes me realise that my “eLated Mundo” is really a bike for the enthusiast. More pedaling, more gear changing and more noise. My wife for example is an Ok bike rider but she has just not been able to come to terms with riding the heavier, longer, more gearchangier Mundo. I think for your average non cycling person the hub motor style bike is a compelling ride and makes a strong case for the ebike in general. Now all we need is reliability, good aftersales backup and reasonable cost and these things will be everywhere!

Brake 4

June 21, 2010

Just a quick and hopefully final update on my rear brakes.

I got my first puncture last week in the rear (Kevlar tyres or not this nail still got in!) so I took the opportunity to have another look at the rear brake. Basically I tried a bit harder to mount the 160 mm bb7. But really it was never going to mount well, ie have the caliper grab the disk correctly without significant modification of something so i have gone back to the 185mm. Which is still working fine and locking up the rear wheel whenever I want.

Anyhow given that Yuba seem to have changed the rear disk mount point in recently sold frames my experiences with rear discs are probably a bit out of date. Check some of the other Yuba links in my blogroll for pics of the new offset mounting point, and some pics of some great new mundo creations!
