It has taken more than two years in the planning and six months in the fitting, but today I pedalled electric on an upright.
I had it on the Trice, and fitted a Windcheater fairing, but didn't feel comfy about going out on it. Deciding that I am going to have to work my way back to the darkside I tried the motor against three of my upright frames and it fitted none of them.
In the cellar I had a skip recovered Ammaco frame that, besides the top tube being parallel to the ground, is the same dimensions as my On One frame that is a nice fit. The LH thread on the BB was knackered but BB threads aren't needed with the Bafang. Assembly was slow as I stripped bits off other bikes to make this one whole but it went together easily.
Aunty Helen's blog provided the settings to use: five levels of assist and 25kph max speed. (you can have 9 levels of assist and 42kph if you wish) and then I waited two weeks for a day that brought together low traffic, no rain or ice and no man flu. Today was the day.
Only five miles travelled, only one very close overtake, and a very enjoyable little ride after a long time without. I did two significant hills to experiment with gears/assist and was very pleased.
I was normally at level one or two with the assist and level 4 made a very noticeable difference uphill. It gave rise to the thought that each of the Alfine 8 gears now has five levels available if the motor is turned on. Something like 48 gears, or is that too simplistic?
The thumb throttle didn't work because when I pushed it with my thumb the whole thing revolved around the bars. The mechanic hadn't tightened the clamp. I'll have words with him.
Big thank you's to the people who helped out here, and on other threads: Kim, Aunty Helen, JennyB, FrenchTandem among others.
Tomorrow is saddle repositioning and fitting a Thudbuster. Even six years post op low pressure Big Apples and a Rido saddle are not enough.
