First proper ride of the year today!
After 10000km my ebike transmission was skipping so much that it was unrideable, and the chainwheel looked very worn. I replaced the chain and reinstalled the original crankset, but the cassette was beyond saving too.
EM3ev in Hong Kong have a lot of interesting parts for the BBS01/2. I got a couple of spare chainwheels (they also have a blingy CNC version) a speed sensor extension cable, and a power cutout button because I had been running without brake sensors.
The motor and new parts went into my old Xtracycle-equipped load-hauler, Oli. He'd had a front hub motor in a previous incarnation, but that had always struggled a bit on the hills round here.
I'm recovering from a bad cold and a strained back , but this morning I went for a 10k shakedown ride, slow and easy, maximum assist all the way.
Through-the-gears assist + long wheelbase = a match made in heaven!
This must be the most relaxing bike I have every ridden, and wonderfully stable on the icy road. I was ghost pedalling up the steepest hill, feeling the rear tyre slip if I tried to push any harder. Only 17 km/h average speed and 91 watt hours used, but who cares?
The new cassette arrived for the 'fast' bike. 12-36t, so it now has a lower low than Oli - 26" v 32". I took a spin on that when the ice had cleared, and only got halfway up the bastard hill.
Update: Thursday morning. Out on the 'fast' bike again before breakfast. Worked hard enough to be Definitely Not Fun and got all the way up the hill this time. The 10k took just over 35 minutes on Oli. I don't have an exact time, but this time was at least 5 minutes slower.
I'll try again when I'm fitter. My fastest recorded unassisted time for the loop was under 30 minutes - 22 minutes in Shadowfax mode.
