Thanks for reaching out to Bicycle Power Trading! You're welcome to contact us for any assistance you may need.
Depending on the age of your unit, it may require a new belt and pulley wheel. Not to worry though, as we currently have these units in stock. Alternatively, you're welcome to purchase these service items online via bicyclepower.co.za and do the replacement yourself.
What's great is that the belt ships with all the tools needed to open the non-drive side cover. So, you'll have everything you need to get the job done.
If you have any further questions or need additional information, please feel free to get in touch with us. We're here to help!
