How to Fit

 Installation is simple and more-or-less anyone can do it! Once installed, the power pack can be instantly attached or removed.

What's included

The kit includes everything you need to convert your bike into an eBike, including the motor wheel, battery, controller and charger. 

Compatibility

It really is compatible with any type of Brompton: including any number of gears, and any handlebar type.

How it works...

Power from your handlebars to the wheel

The Swytch Power Pack fits to your handlebars and sends power to a motor in your front wheel.

It is pedal-assist

the power comes in as you pedal thanks to an easy-fit sensor that detects when you're pedalling.

What's In The Box?

 

1) Motor wheel

2) Power Pack

3) Handlebar Mount

4) Pedal Sensor

5) Charger

6) Instructions

7) Brompton Peg

The Swytch kit includes everything you need to convert your bike, unlike many other kits that require you to buy extra parts (such as the battery and charger) separately. So the price you see is the full price you need to pay, no hidden extras!

There are some optional extras you can order (see below) but these are not required to get the full Swytch experience of riding a state-of-the-art electric bike.

Optional Add-Ons

Twist Throttle

Motorbike style twist throttle that fits to your handlebars. Twist and go to get motor power on tap! Off-Road use only.

Thumb Throttle

Lever style thumb throttle that fits to your handlebars. Twist and go to get motor power on tap! For Off-Road use only.

Inline Brake Sensors

Extra safety for bikes with regular cabled brakes - feed the brake cable through for instant motor cut-off when you brake.

Hydraulic Brake Sensors

Extra safety for bikes with hydraulic brakes - sticks to your brake levers to detect when they are pulled.

Torque Arm

Extra safety for bikes with carbon forks, or for use with a high power motor to hold motor tightly in place.

How To Fit

Tools Required:

Just a couple of allen keys and a spanner, that's it!

Plug and Play

The full kit arrives pre-assembled and ready to go. The wheel is built to your wheel size, and the power pack is charged and ready to use.

1) Swap the wheel

Step 1 is to simply swap your regular wheel with the Swytch motor wheel. You'll need to swap the tyre over too don't forget!

2) Fit the handlebar mount

Next, just fit the handlebar mount to the handlebar and tighten it securely.

3) Fit the pedal sensor

Clip the magnet disc onto the pedal, and stick the sensor to the frame. The sensor detects when you're pedalling because the magnet disc moves past it. That way, when you pedal the motor can activate.

And you're off!

Just clip the power pack onto the bracket and you're ready to go!

FAQs

What's my Wheel Size?

Most bicycle wheels are 26" or 28"/700C, so it's probably one of these.

If so - great news we offer these sizes as standard. If you have a different size you may need a custom build.

Read full FAQ for more info and how to check your wheel size

How much range will I get?

The quoted range is based on medium usage (using it power level 5/9), and with pedalling too.

The actual amount of range you'll get depends on many things, including how much you pedal!

Read full FAQ for more details

 

When will I receive my kit?

Currently we are accepting pre-orders with guaranteed delivery times because new stock is on the way.

You'll get regular updates as the kit gets closer to the email you registered when you order

What is the top speed?

The top speed of our regular kits is limited to 15Mph to comply with UK and EU laws.

The off-road high power kit can be de-restricted for up to 30MPH for off-road usage only.

Does the power pack lock in place?

We deliberately designed the power pack so that it can't be locked in place, as this might just encourage thieves to vandalize or break it to steal it.

Instead, it's super easy to pop off and take with you.

What hills can it climb?

The motor has 30Nm torque, which is a lot for a 250W kit

You can climb typically up to a 20% gradient without any sweat, but it depends on your size, weight and pedal power.
