At first I was looking at oneWheels and EUCs but then decided the cargo in my backpack would be too much to drive it safely and attaching a bike trailer would be awkward.

Then I started looking at bikes with front baskets/paneers but still smaller form factors.

My goal would be to carry sound equipment and lithium ion to power it with round trips being around 10-15mi.

¡Then I went to a local music festival where someone pulled up on an electric bench! I thought I took a photo of it but I guess I did not. It was a standard wood picnic bench but it was on leaf springs with car tires and it had an electric motor and it was used to drive from the camping area to the stage area.

Cargo bike payload looks like an EUC to me now, after seeing this bench and the amount of speakers it could hold. I was curious how they even drove it to the festival and as they were leaving I see them hooking it up to a ball hitch on a 4 door car.

¿What bikes would you recommend to carry a sound system load out? Ideally something a DJ could play while I'm driving this thing 2-7mph in a streets blocked off for cars first friday block party thing the city does. ¡3 wheelers are fine!
