"Scootering" my bike

[Catrin]

I almost always start with my butt on the saddle, but that's b/c I like to rest sitting on it, rather than standing over the bike. I have long (err...big) feet so it's not too hard for me to touch one toe down and keep the other foot clipped in while still sitting.

I have long feet, and I've proper leg extension on my road bike. I need to raise it a bit on my Mtb bike but have to learn a new way to start it. I've seen the videos, the problem is doing it...
