Yes, I understand that, but how much do they assist you up a one chevron hill at 5mph?
How much of assistance is there to take the puff and strain away?
Can you get up a one chevron hill without being out of breath?
It seemed to me that the couple today sailed up the hill. It's a strain just walking it.
Not saying in the least that they had illegal eBikes, but it occurred to me that hills become so easy with an eBike it must take the effort clean away when riding in Cornwall. It must make the hills appear flat.
There are different power profiles in various e-bikes. Some give a gentle and gradual assistance that's related to your own effort, measured with strain gauges in the BB or elsewhere. To get the motor's 250w you have to output a lot of power yourself. Most of the racey style e-bikes are like this, so it still feels like proper cycling but with stronger legs. It's not easy to get anywhere near 250W assistance out of them unless you're trying very hard yourself.
On the other hand, the ladywife's has a "red" setting (top of three "on" settings) that will momentarily give up to 400W. It won't last as the motor gets hot and you can hear the battery draining with an electricity-gurgling sound, so the clever bike shuts it down again.
It's meant for those momentary 1 in 4s found on wicked Blighty countryside roads, especially on the inside camber of switchbacks.
Other e-bikes, especially the heavier continental tourer style with a big 70Nm BB motor and 500 or 750Wh battery, have a different profile, such that their power is readily available in large amounts even if you aren't yourself putting in a lot of effort. Some just seem to have a set-power at each setting or level of assistance and don't seem to measure your own power output. In those cases, you just have to turn the pedals to keep the power on - or so it seems.
If you're fairly fit but not enough to enjoy seriously hilly cycling (especially with fitter people) then a racey-style e-bike is ideal. It adds just enough on the hills so you don't get dropped (or can even show off a bit). Every hill isn't a serious physical trial needing an oxygen cylinder waiting at the top. If you're essentially unfit but want to cycle distance and hills then a bike with more assistance at each level, with no miserly output if you don't try hard yourself, is better.
Dandy horses for courses.
