    Interesting frame - it does not have provisions for a rear disk brake, but seems to have some odd bosses for rim brakes. The chainstay cutout suggests its a fatbike frame, but there's a cable stop for a front deraileur, which many fatbikes omit for clearance reasons. So its quite an odd combination. – Criggie Jan 6 at 7:14

    Looks like maybe a trials frame? No seatpost clamp as well, indicating a locked on seat (with expander through the seat)? – Deleted User Jan 6 at 16:17

    I'd agree with some sort of trials frame as the brake bosses are 4-bolt as used for Magura hydraulic rim brakes and they were very popular for trials bikes. Chain-stay shape would mean you could run big fat trials tyres. Could be a Monty? But that's just a guess based on trials bike and Monty starts with an M. – DecSim Jan 6 at 17:02

Thanks to DecSims comments to the original post I think I'm close.

Here's the logo
enter image description here

It is a Monty trial bike.
The bike pictured is a Monty B221 X-Lite Mod.

My best guess is that it's a 2002 Monty 231 x-lite
