Here's Vintage's off-road e-bike:

Hard News: Up with the Pacer: embracing…, in reply to
I recently saw a guy coming up New North Rd to Kingsland and was clearly travelling at around 30km/h, he wasn’t fooling me by pedaling hard. He was clearly riding an e-bike that was several times more powerful than anything I’ve ever been on.
I think torque sensors make a difference – fitter riders will go faster. I pedalled hard up Chinaman’s Hill the other day and did 30km/h (although not all the way).
But check out this bike spotted in Wellington by Finlay Macdonald. I’ve never seen anything like it. And that “3000 watt race mode” looks … interesting.
PS: It's not actually vintage – that's the name of the maker.

Too loud for the room, I thought. Although it did sound quite good back by the ladies' loos (i.e.: basically in the next room).
But mostly, that bloody venue needs sorting out. Either they fix the bottleneck or lower capacity, or someone's going to get hurt.
Great pics tho!

This isn’t some horribly unusual thing to do, to get paid to review something, and it can be interesting in its own right, as it was in this case.
My original pitch was for the banner campaign that ran (as part-contra for the bike) but the agency came back asking if I could also write a couple of sponsored blog posts, which I was happy enough to do in this case, given that it was a chance to ride an e-bike for the first time. The second post was about traffic congestion, which was the client's request, but my research and conclusions.

Good explanation, thanks. This:
Anyway, what’s the difference? A cadence sensor detects if you are pedalling, tells the controller, which then supplies motor power up to the limit you have set on your display. Most cadence sensor bikes also have throttles. A torque sensor bike detects how hard you are pedalling and the controller/motor will then provide a multiple of that pedalling force, from perhaps 50% (Eco) to 300% (Power).
The outcome of that is with a cadence sensor, you only have to pretend to be pedalling to get full power. You could also simply use your throttle. With a torque sensor, you are always helping. Even at the 300% level you are still providing 1/4 of the power yourself.
Perhaps another way to describe it is that a cadence sensor is a constant speed bike (to the limit you set on your display) while a torque sensor is a constant effort bike (the speed will vary if your effort changes).
And very much this, for me:
It feels more naturally like a bike – you control the speed through your pedals, you don’t have to fiddle with the controls much
