Although I’ve not done it in one session yet, two long-ish sessions have allowed me to give a fairly decent range estimate on the D2S.
It started flashing a single red light at about 24 miles, and shut off totally just shy of 27. So essentially it’ll ride a marathon.
That’s a little under the claimed 50km range, but still better than I expected with me being somewhat heavier and bigger than many riders, and definitely heavier than the average Indonesian/Chinese person (who are, after all, the world’s biggest buyers and users of e-bikes).
Anyway, here’s some pretty photos from my travels.
