Taste is in variety, that's why we have brought several Retro models that are very similar, but at the same time very different. Don't be fooled by appearances as at first glance they seem identical. We are pleased to present: RetroEU, Retro-Extends and Retro-Plus .

The biggest difference between the models is found in the painting : the RetroEU It has a simple but stylish frame; in the Retro-Extended It has an extension so you can place whatever you want, with the option of adding a second seat and sharing the experience in couple ; in the Retro EU Plus It has some details that give it a more Sport.

All can be configured with a multitude of accessories, they have Bafang motors from 250w36v, 500W48v, 750W52v or 1000W52v, Samsung batteries from 36v13AH to 52V21AH, with maximum speeds of 25km/h to more than 50km/h.

But there is still more, all come equipped with a front and rear light, also configurable. And a thumb throttle on motors over 250W.

Basic motor configuration (250W) It is fully compatible with EU regulations. Retros fall into the "EPAC" category, which means that you can ride it like any normal bicycle, on public and private streets and without any type of license, registration or vehicle registration.

For the rest of the motors with powers greater than 250W, they can be sold legally in the EU, but they cannot circulate on public streets without prior registration of the vehicle with your local traffic administration. They can legally be considered a "moped" and therefore need a license and insurance. All this is the responsibility of the client .

We recommend the 250W motor for all users in the European Union. with the Mario Fork II suspensions, which give it a radical look.
