DYU C2 (EU) Electric Bike

Perfect for tight apartments: Unboxing the C2 was a breeze. The box was compact and everything was well-packed. I was riding within 15 minutes after attaching the pedals and handlebars. The folding mechanism is so smooth that I can stash it under my desk at work without anyone noticing. (Attached a photo of it folded next to my office chair)

Surprisingly stable for small wheels: Took the C2 for a 15km ride along the river path. The 16 by 2.5 inch tires absorb bumps much better than I expected. I felt completely stable at 25kmh, even over some cracked pavement. My friend who has a larger e-bike tried it and said he was shocked by how planted it feels.

Realistic battery feedback: The 48V 7.5Ah battery gives me about 30km of range using mostly throttle. I weigh 75kg and ride on mostly flat terrain. That is plenty for my round trip commute plus a detour to the grocery store. Charging takes about 4 hours, so I just plug it in at my desk.

Hill climbing test passed: There is a 10 percent grade hill near my house where my old bike would slow to a crawl. The C2 maintained 20kmh up the entire hill without me breaking a sweat. The 250W motor is clearly tuned for torque rather than just top speed. Very impressed for such a compact bike.

Seamless multi-modal commute: I ride 3km to the train station, fold the C2 in under 10 seconds, carry it onto the carriage, and then ride another 4km to my office. The bike fits perfectly under the train seat. The folded size is 815 by 435 by 565mm, which is tiny. No more walking from the station.
