E-Bike Buying Guide: How to Choose Your SUNNIGOO Electric Bike

How to Choose Your SUNNIGOO E-Bike: Buying Guide 2026

All SUNNIGOO city and folding e-bikes are EU-standard pedelecs: a 250W EU motor with pedal assist limited to 25 km/h, so they are legally treated as bicycles in most EU countries. This guide helps you pick the right model in three minutes.

2. B1 vs B3 vs B5 — Same Price, Different Characters (all €1,049)

  • Choose B1 if you want the simplest ride: flat commutes, elevator-and-closet storage, and the lowest weight to carry up stairs.
  • Choose B3 if your route includes wet or loose surfaces: hydraulic disc brakes give shorter, more controlled stops than mechanical brakes.
  • Choose B5 if one charge must last your whole week: the 600Wh battery is the biggest of the trio (50-80 km pedal-assist, up to 120 km combined), and the front basket + rear rack make it grocery-ready.

All three share 20 inch x 4.0 inch fat tires, a 250W EU-standard motor and a removable 48V battery, so comfort and ride feel are close — the deciding factors are braking, range and cargo.

3. Pedelec Regulation Basics (EU)

  • Standard pedelec (EPAC / EN 15194): 250W continuous rated motor, assistance cuts off at 25 km/h → treated as a bicycle in most EU countries. All B1-B5 and FINER M-series models fall in this class.
  • S-Pedelec (L1e-B): assisted speed above 25 km/h → classified as a moped: registration, insurance and a helmet may be required. The C91 reaches 55 km/h and is not a standard pedelec — please confirm your country's regulations before purchase.
  • Rules vary by country (helmet rules and age limits). Check your national transport authority's website before riding.
