There’s been no real shift away from street riding.. it’s just not watered down by daft large wheeled bikes, gears or stupidly powerful brakes anymore.
MTB Dirt Jumping has finally gone in the right direction IMO with riders like Aggy and Lacondeguy pushing and building ridiculous FMX style trails.
BSX/4X was only ever properly popular in the South of the UK where there are very few places suitable for DH (and now Enduro).
Fashion means it won’t stop folk turning up to Chicksands on Capra’s and Spectrals.. it’s definitely an improvement from their Demos and V-10s.
I used to ride Chicky on my Demo 9! In my defence though I wasn’t local and it was the only bike I had.
MTB street has alway looked wrong – so much better when done on a BMX. It was even worse when MTB riders where trying to grind stuff.
BSX/4X/Dual could be added to this list – all very cool at one point but have kind of died a death.
Just thought of a few more…
Le Toy (horrible DJ / Street frames)
Rocket (I think – old school dual/jump frames)
