Very interesting. Price landed in Aus should be less than $300 by the looks. Much cheaper than PVL, Powerdynamo etc but this has much less hardware involved so should be less costly to manufacture.
Don't know how long Runtronic has been making products but does look a little bit like a cottage industry product so hopefully manufacturers backup support is there is needed.
Requires a 5v nicad battery so I guess VMX bikes will be total loss. Just need to have a spare charged battery on hand - shouldn't be too difficult to remember!
Is it a simple process to mount the magnet in the flywheel? Drill a hole and glue in the magnet?
