After comparing a few options, I went with the MS Energy StreetFlex i20 — good call. Great for longer weekend rides as well as the commute. At 22.1 kg it's easy enough to move around and store. Already thinking about which model to get next.

The MS Energy StreetFlex i20 has quickly become part of my daily routine. At 22.1 kg it's easy enough to move around and store. Top speed is right around 25 km/h, which feels well controlled rather than twitchy. Customer support was responsive when I had questions before ordering.

Picked up the MS Energy StreetFlex i20 last month — no regrets so far. Pedal assist kicks in smoothly, doesn't feel jerky at all. At 22.1 kg it's easy enough to move around and store. Customer support was responsive when I had questions before ordering.

First bike I've owned in this category, and the MS Energy StreetFlex i20 set the bar high. Charges fully in about 5h, which fits my schedule. Top speed is right around 25 km/h, which feels well controlled rather than twitchy. Exactly as described on the product page — no surprises.

Solid choice if you're on the fence about the MS Energy StreetFlex i20. Pedal assist kicks in smoothly, doesn't feel jerky at all. The 0kW motor has plenty of pull, even on inclines. A bit heavier than I expected, but performance makes up for it.
