Quick message from Sentient:

NOTE: This is an ADD-ON line for a complete bike purchase only.

If you want the complete bike, but with a dynamo instead of the normal front hub then add this line to the basket and we will swap the wheel out.

If you just want a the dynamo wheel without a bike, then add this instead.

Lights sold separately!

Here's what Omnium has to say:

A human powered light generator!

No more bike light hassles like recharging them, removing them when leaving the bike, and getting caught in the dark with out them!
