What We Do?
How I can help on your next ride
Mobile Devices Charging
Attach me to any dynamo bicycle, pedal and charge! I am responsible for regulating the generated energy, so you and your devices are always safe.
Battery Storage
When you are not charging or when you generate more power than needed, I store the excess electricity in the two batteries for future use.
Crash Detection
I hope you never need to, but in case of a bicycle fall and no response to the alarm, I can inform a loved one that you are in danger and send GPS coordinates.
Adaptive Resistance
I can decrease the added resistance, so you don't need extra effort when riding uphill, and increase the added resistance for better performance when riding downhill.
Personalization
You can set me up to serve you according to your preferences. Thus, you can decide the crash reaction time for alarm deactivation and incline range resistances.
Urban Space Optimization
Portel will collect statistics on where cyclists ride most often, their average speed, where they make emergency stops, and more, and provide this data to the municipality so they can optimize roads for cyclists.

Have Any Questions?
Portel comes with two high-capacity lithium-ion batteries. The exact duration for which they can store energy varies depending on usage and the amount of energy generated.
However, under optimal conditions, the batteries can store energy for an extended period, ensuring you always have backup power when you need it.
