Design and power with a great pair of fat tires. Start riding the most radical and highest-performance e-bike on the market with off-road or road tires, motors of up to 1000W power and a unique frame.

In January 2021, we decided to start a new journey and set up a site where you can find those sliders that leave no one indifferent.

For the past few years, we have been working day and night to create BKSildes, seeking partners around the world to offer the best quality and most fun moving experience.


Are you a Slider? Join the #BKSlides community, simply the best e-Slides.


We bring you an e-bike that will make your friends follow you, your mother look at you with a look of... again!!, and your partner will ask you, What about mine? We are here to delight you and amaze the people around you, while offering one of the best e-bikes on the market.

The Retros are built with a strong and resistant aluminum frame, capable of supporting up to 120kg of weight. Its amazing design allows it to accommodate passengers from 1'50m to 2'00m tall

Move in style. Start driving with attitude. Get anywhere in an instant with motors from 250W to 1000W and more than 50km/h. The best batteries in their class: Samsung guarantees quality and up to 60km of autonomy on a single charge.

The retros have the best you could ask for: easy-to-use Shimano Altus 7-speed gearbox for a smooth and pleasant ride; 860C LCD screen with USB charge hub to control all electrical parameters; and a Tektro hydraulic disc brake system for safe, clean braking.

You can configure the color from a wide selection of colors.


The Retros boast very powerful motors of up to 1000W combined with impressive batteries of up to 21AH and 52V and a state-of-the-art controller in all models. You will feel the acceleration and speed instantly. A super fluid experience when pedaling.

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

Your safety is our priority, which is why we have equipped the new generation Tektro hydraulic disc brake system as standard, including levers and calipers.

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 in the frame : the RetroEU has a simple but stylish frame; The Retro-Extended has an extension so you can place whatever you want, with the option of adding a second seat and sharing the experience as a couple ; The Retro EU Plus has some details that give it a more Sporty appearance.

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's even more, they all come equipped with a front and rear light, also configurable. And a thumb throttle on motors over 250W.

The basic motor configuration (250W) 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 of this is the responsibility of the client .

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