This is an inaugural year Big Fat Dummy frameset I bought on clearance and kept in a box until I adopted it as a Covid lockdown project. After watching a Grin video on multi-motor setups, I got the idea in my head to make it all-wheel drive. And with the help of the folks at Grin, it worked great! (until I ripped out the brazeons I used for the torque arm, which is why some photos only have one hub motor.)

I use this as a grocery getter, passenger hauler, box truck, and most importantly it hauls a 4000w soundsystem on Pedalpalooza rides all over the city. Also my little fuzzy buddy Ranger has been riding bikes since he was 3 months old, and is never happier than when he's on the back of the bike.
