# How can we help with your CAROL?

Tell us which bike you have and we'll show you only the guides that apply to it.

## Find help for your bike

CAROL 1.0 and CAROL 2.0 work differently, so the right steps depend on which one you own. Your serial number tells us.

### Still stuck?

Send us a message and include your serial number. You can also send diagnostics straight from the bike, which tells us far more than a description.
