There's a mountain there that's 10 miles high. However it's a conical volcano whose base is 100 miles across, so the average gradient is only 1:10.
However, with lower gravity than earth there's tremendous potential for getting the biggest air of your life. Only it wouldn't be actual air, more like thin CO2. Come to think of it, the lower air pressure would allow for phenomenal speeds on road descents. If there were any roads. Or trails, for that matter. I suspect that a lot of trailbuilding work would be required. However, there are proably some sick drops into those canyons.
Has he been looking at the ugly bikes thread?
Looks to me like you would be overbiked on anything other than a rigid fixie 29er.
1:10 gradients + 1/3rd gravity sounds brilliant for climbing. It's nice and dry too, if rather chilly.
However, the dust is rather like talc and will ruin your hubs, BB and headset in half an hour. There are lots of deep dust traps in between the boulder fields too.

Scope for some north shore then.
There's some really cheeky non-bridleway stuff
Olympus Mons would be a great ride 🙂
best thing no ****ing walkers anywhere
... never met her.Olympus Mons would be a great ride
Also very very salty amd akaline, so steel framed bike out of the question. Plus coming back home, round trip of 9 months, immigration would be a nightmare! Heathrow would lose you bike and bags.
