Sekine Medialle Ten Speed

Putting new life into an old friend

You have seen them. The advertisements in Youtube and Facebook. The British accented fellow skidding up to the forefront of your screen. Skids to a stop and say, “This is a Swytch bike!” The advert continues and within twenty seconds convinces you that any bike can be converted to an ebike.

So we decided to pay the price and test out this claim and convert a 1978 Sekine Medialle ten speed road bike into an ebike. The results, were stunning!

Converting a old ten-seed road bicycle into electric

Seven years ago I took my old 1978 Sekine Medialle ten-speed and I upgraded it with modern parts. This mean’t that it was now equipped with 700c Wheels, modern brake levers and updated brake calipers. Now it was time to update it again, this time with POWER!

We order the kit from Swytch Bike as a 700c wheel, complete with upgraded battery and upgraded controller. The kit itself came to just over $1000 CAD delivered.

It took three months for the kit to arrive, and the adverts kept popping up on my facebook feed. At first glance if you are not used to building bikes the kit could be intimidating. Properly labeled and neatly packed, the parts where plenty. We were ready.

The challenge on our trusty Sekine was the front forks. The Swytch kit is a front wheel mounted motor drive, so the flatted axles were too wide for the drops. Options were; to consider a new fork, which would be taking away from the vintage look of the Sekine, or using a trusty Dremel tool.

Since the Sekine is a Carbon steel frame-set, the Dremel was chosen.

A ‘Readers Digest’ list of steps looked like this:

  • Remove the front Wheel
  • Change the rear wheel to match style. This was a necessity due to the fact the Sekine’s existing rims were black and the Swytch Kit rims were silver alloy.
  • Install Cadence Sensor on seat tub non-drive side and mount the orbital magnets to the crank arm.
  • Install battery mount to handlebars
  • Install a second accessory mount onto the handlebars. This was needed to hold the LCD Display panel/controller since the Sekine has a drop-bar and the controller mounting diameter was tool small to attach on the bar.
  • Charge Battery
  • Connect all cables. They are all colour coded
  • Zip tie the loose cables to make it all pretty.
  • Bench test the system to ensure it all works.
  • Test ride.

The total time needed to properly do all those steps came to 2.5 hours. The first ride was quit a surprise. The bike is governed to 32 km/h but it was apparent it wanted to go faster. Acceleration was brisk, even with my senior male body mass.


  • When ordering the Swytch Kit, always get the bigger battery to ensure the best range.
  • Either controller is fine. Our LCD was bright and easy to use. The standard kit controller is a double LED selector and can save you some money.
  • Consider ordering a second battery charger as a back-up.
  • Have your kit professionally installed.
