The retro has the best you could ask for: easy-to-use Shimano Altus 7-speed gears for a smooth and enjoyable ride; 860C LCD display with USB charge hub to control all electrical parameters; and a Tektro hydraulic disc brake system for safe and clean braking.

You will be able to set the colour from a wide selection of colours.

The Retro bikes boast very powerful motors up to 1000W combined with impressive batteries up to 21AH and 52V and the latest generation controller on all models. You'll feel the acceleration and speed instantly. A super-fluid pedalling experience.

It also includes a SMART LCD 860C colour display with a multitude of programmable assistance parameters by default and USB connection to charge your mobile phone.

Your safety is our priority, which is why we've fitted the new generation Tektro hydraulic disc brake system as standard, including levers and callipers.

Variety is the spice of life, that's why we have brought you 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 look identical. We are pleased to present: RetroEU, Retro-Extends and Retro-Plus.

The biggest difference between the models is in the frame: the RetroEU has a simple but stylish frame; the Retro-Extended has an extension to fit whatever you want, with the option to add a second seat and share the experience as a couple; the Retro EU Plus has details that give it a more Sport look.

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

But there's more, all come equipped with a configurable front and rear light. And a thumb throttle on engines over 250W. And a thumb throttle on engines over 250W.

The basic motor configuration (250W) is fully compliant with EU regulations. The Retro falls into the "EPAC" category, which means you can ride it like any normal bike, on public and private streets and without any kind of license, registration or vehicle registration.

For all other motors with power ratings above 250W they can be legally sold in the EU, but cannot be ridden on public streets without prior registration of the vehicle with your local traffic administration. They can be legally considered as a "cliclomotor" and therefore need to be licensed and insured. All this is the responsibility of the customer.

We recommend for all EU users the 250W engine with Mario Fork II suspensions, which give it a radical look.
