Revvi Chain - To fit Revvi 16" electric balance bikes

Chain 16" - To fit Revvi 16" electric balance bikes.
 
To fit a new chain on a Revvi 16" electric balance bike, you'll need to replace the existing chain with the appropriate size for the 16" model. You'll also likely need a 15T front sprocket and potentially special tools to remove the freewheel. The process may involve removing the battery plate and speed setting bung on the 16" and 16" Plus models. 
Here's a more detailed breakdown:
1. Identify the correct chain and sprocket:
Chain: Ensure you have a chain specifically designed for the Revvi 16" bike. 
Sprocket: You'll need a 15T front sprocket, which is included in the 15T front sprocket and chain kit. 
Motor: The kit mentioned in the search results is for bikes with 100w or 170w motors and will make the bike significantly faster and improve acceleration. If your bike has a 250W motor, this upgrade will not further improve performance, according to a product page on Revvi.co.uk. 
2. Necessary Tools (potentially):
Freewheel removal tool or a vice and punch: These are needed to remove the freewheel from the wheel to change the sprocket. 
Chain breaker: May be needed to cut the chain to the correct length, especially if you are replacing it with a new one. 
Chain link pliers: May be needed to install the new chain. 
3. Installation Process:
Flip the bike: Turn the bike upside down to access the chain and related components. 
Locate the speed settings: On the 16" and 16" Plus models, you'll need to locate the battery plate and the rubber bung covering the speed settings. 
Remove the bung: Carefully remove the rubber bung to access the speed settings switch. 
Adjust speed settings: Set the speed to your desired level (8mph, 10mph, or 12mph). 
Install the new chain and sprocket: Follow the instructions specific to the 15T front sprocket and chain kit, potentially using the tools mentioned above. 
Ensure proper tension: Make sure the chain has the correct tension after installation. 
Test the bike: Check the speed and acceleration after the installation.
