Real Rider Reviews

The Dolphin+ is incredibly solid and well built. Easily one of the most reliable fat tire folding electric bikes I’ve owned.

Great quality overall. The ride is stable and comfortable, especially on rough roads. Perfect all-terrain folding e-bike.

I use it for daily errands and weekend rides. It’s a folding electric bike with fat tires that handles everything.

Battery life and ride comfort are excellent. Slightly heavier, but that’s expected for a fat tire e-bike with this power.

Super stable and confidence-inspiring. This all-terrain e-bike performs great on gravel, pavement, and even light trails.

I upgraded a few parts, but overall this is a durable folding electric bike that holds up really well over time.

If you want comfort over speed, this is it. The fat tire design makes every ride smoother, especially in the city.

Great value for the price. A powerful folding e-bike that feels sturdy and reliable for everyday riding.

Aviso: Tres métodos de carga

 1. Puerto de carga de la batería del poste del asiento (solo para cargar la batería del poste del asiento)

2. Puerto de carga de la batería del cuadro (solo para cargar la batería del cuadro)

3. Puerto de carga inferior del cuadro (se pueden cargar dos baterías, orden de carga: primero la batería del cuadro y luego la del poste del asiento)

La distancia difiere según el terreno, el peso del ciclista y el modo de potencia que esté utilizando (solo pedal, aceleración máxima o asistencia de pedaleo).

Para un Dolphin de una sola batería: el alcance es de aproximadamente 25 a 60 millas con una sola carga utilizando principalmente energía eléctrica.
Para un Dolphin de batería dual: el alcance es de aproximadamente 40 a 80 millas con una sola carga utilizando principalmente energía eléctrica.
Si utiliza el PAS, el kilometraje puede aumentar. Algunos ciclistas pueden alcanzar más de 60/80 millas cuando andan en modo de asistencia al pedaleo.
