TongSheng TSDZ2B 48V 350W/500W Torque Sensing Mid Drive Motor

$536.00

Motors above 250W

Please note a motor output exceeding 250w and speed assistance exceeding 15.5mph means it cannot be used on UK public roads without first obtaining type approval, insurance, tax, displaying a number plate and undergoing an MOT.

In the UK, only converison kits that comply with EAPC Regulations can be used on UK public roads without tax, insurance or registration. A conversion kit above 250W can only be used off-road on private land. 

You can find out more about EAPC Regulations here: https://www.gov.uk/electric-bike-rules.

For the avoidance of doubt, you will be responsible for obtaining such type approval, insurance, tax, registration and MOT.

Please read before ordering

Once a kit has been fitted, a refund can't be processed as the item has been used.

Please contact us before ordering to make sure the kit will work on your bike.

Cyclescheme Vouchers

Cycle to work Scheme

The Cycle to Work Scheme is a Government-backed initiative to encourage people to cycle to their place of work, and consequently reduce environmental pollution. It's also a way for you to save money on the cost of your cycle and spread the cost over a number of months, through your pay packet.

How do I get a conversion kit through Cycle to Work?

If they haven't already, your employer needs to register with one of the Cycle to Work Schemes in order to offer this benefit to their employees. Once they are signed up with a scheme, the employee needs to find a cycle retailer who is also registered with that scheme.

Electric Bike Conversions is registered with four of these schemes - Bike2Work, Cycle Scheme, Green Commute Initiative and CyclePlus. You'll see our name listed on each of these schemes such as Earth Cycles or Bike Bros. These are other names we trade under, but we are the same company.

The paperwork required differs for each scheme and should be available from your employer or from the links below for each scheme:

Green Commute Initiative - Our recommendation!

Cycle Plus

Once the necessary paperwork is completed you will usually be issued with a certificate by your employer or Cycle to Work Scheme that you can use to purchase the kit from us. Your employer pays for the conversion kit via the scheme and the scheme then pays us for the purchase once you have collected the kit and provided us with your certificate.

If the kit is being delivered or installed by us, we can receive the certificate digitally. We'll also sometimes ask for proof of ID, depending on the scheme. The cost of the bike is then deducted from your salary over a period of time, but as you don't pay tax or NI on the income that's deducted, you make a saving on what you would pay if you purchased outright. This saving will vary depending on which tax band you fall into!

Due to the cost of running the Cycle To Work Schemes we have to add a 10% fee on top of the kit price, otherwise we cannot afford to be apart of the scheme. Sorry for the inconvenience.

Description

The TongSheng mid drive motor is our new addition to the range. This new motor allows for an easy way to convert your bike to an ebike. This 350W/500W motor is packed with features. Compared to Bafang motors this is also a Torque sensing motor. A torque sensor measures how hard the rider is pedaling to determine how much electric power to push to the bike. The TongSheng Mid Motor gives you more power when you need it most. This innovative motor responds in real time to your pedaling.

The TongSheng TSDZ2B  is the newest model that comes with a two clutch design on the main gear. Main gear disengages from the chain during riding which makes it to ride your bicycle like a mechanical one. The older version (The TSDZ2) only had one clutch design.

Whether you're cruising around town or climbing a steep hill, this motor gives you the boost you need to get where you're going. And because it's a mid-motor design, it's perfect for those who want a more balanced ride. So if you're looking for an electric bike conversion kit that can keep up with your active lifestyle, the TongSheng Mid Motor is the perfect choice.

How do I know if this mid drive motor fits my bike?

This mid drive motor is designed to fit bikes with a 68mm (2.68inch) or 73mm (2.87inch) wide bottom bracket. The inner diameter of the bracket should be not less than 33.5mm.  Most modern bikes sold in the UK meet this standard (but please check).

We also provide a set of spacers to help you adjust the motor to fit your bike.
