I have actually thought about this. In the worst case, I would need a fairly large flatbed that could accommodate heavy bulky items like amps, PAs, and boards along with awkwardly long gear like mic stands. At least my new ebike has a fairly capable motor.

One possible advantage to biking to a gig might be that you could get closer to the venue for loading/unloading? What sucks hard is when you have no choice but to park at a lot several blocks away and haul everything over. This can be the case in old-town touristy areas with little vehicular road access.

For out-of-town gigs, we often carpool. If someone else is bringing the stage gear, I could possibly ebike with fairly minimal equipment to where they're loading the van?

Of course if the venue has a proper stage with sound provided, much is this hassle goes away. At that point, I'd just need my instrument and a small pedal board.
