Sulden - Sketch

This is a sketch from a project I'm working on for a local bespoke motorcycle company.

It's a little different to the styles i'm sued to exploring but I'm really trying to expand my abilities to all kinds of styles of lettering. I've tried to subtly hide a bike in this logo which is new to me too. Let me know what you think to this? It's not supposed to be too obvious but something subtle and unique to the type.

Opinions are much appreciated :)

I'm uploading work on Instagram now so please check that out!
