I wrote a post about #ebike, #router, #brouter, #EV and #hybrid #HPEV cars, where I ask:

* what are good parameters for ebike routing?
* can we improve elevation data for the road network?
* do you know of restaurants, bars, bakeries, etc. that allow for recharging ebike batteries, even for a fee?

#OpenStreetMap could probably include that info.

I'm open to ideas!

Yuba Kombi + Virvolt 900 - a trip review

Editor's note: another dictated1 Last September or October we bought a Yuba Kombi and we took it to a bycicle repairman to install a Virvolt 900, which is a 691Wh battery and a 80Nm, 36V motor. This i

Ebike range depends on each rider and each bike, among other things. I have a spreadsheet that I built up from a dozen or so trips, recording distance and elevation gains for each, along with battery usage. I add further trips sporadically. From that data, I worked out a formula that more or less fits my bike and my level of fitness that says, for a projected ride, such and such a milage and height gain should use about so much battery.

@Cameleopard right; if you can calculate that coefficient, that's good. I'm mostly interested in what's the most energy efficient route for a electric vehicle that can't recover energy going down (ebikes), irrespective of my level of fitness (really bad on that trip; still bad today).

@mdione

Don't know if it's helpful, but for me 10m of elevation gain uses approximately the same power as 1 km on the flat.

@Cameleopard so that's ... a factor of 100 instead of 60? And you should be in good shape, I guess, so for occasional/bad shape people like me it's probably more?

I've cycled most of my life, but I've been unwell the last couple of years and "most of my life" means "since I was about five, in 1958".
