Letterboxing by bike?

Ciao all
Considering purchasing a new mountain bike mainly for use on dartmoor. Have recently moved to exeter and am keen to get into letterboxing. just wondered if anyone else got around by bike on the moor and whether or not it was reccommended?
Cheers

Not 100% sure but I beleve you are only allowed on certain tracks and bridle paths. Not sticking to these could be subject to a £400 fine. Hope someone else know s more.

I don't know about the fines but I do know that cycling on the moor off track is an absolute no no without permission as the wheels do cause a lot of damage and the moor can be slow to recover from such damage.

As for an aid to letterboxing - I dont believe it is a good idea as you will have to leave your bike to go and collect boxes leaving your bike open to the light fingered types out there

There are quite a few cycle tracks across the moors that you can use for letterboxing. I have ridden my bike up the road to the Avon Dam, then chained it to the railings and gone off letterboxing up and around Broad Falls. Also you can ride along the disused railway track going all the way up to Redlake from Western Beacon area down the South end of the moors. You can also ride along the Princetown Railway, chain your bike up and get a few along there. And you will definately need your bike to ride along the ring road out to Cranmere Pool area once the Duchy closes the road

I have often gone along the tracks on Dartmoor where you are allowed to cycle, and left my bike and walked on. But make sure you hide the bike. Lucky most people who steel bikes are lazy people so do not go far from car parks. Please do not cycle on open moorland, because you can do a lot of damage to wildlife and the ground.
