Other - Is it Possible to Ride a Bike on Mushrooms?

[meatbag]

Hi, my garden gnome wants to plan his first trip, he's found a few nice places to go and relax that are deserted at night and rather nature-ish. The only problem is he can't get there by any means other than a bike. Walking would take him a long time (especially since his little gnome legs can't carry him very fast). So, he would just like to know, is riding a bike while tripping possible? (If it helps, he would probably be riding a bike in a park that is quite dark in the night)

Also, he doesn't want to take alot, since he is rather nervous, would 1 gram be sufficient? If not, then please suggest another does (he is rather skinny, short and about 52 kilos.)
