Yeah, @Ifallalot just get the home depot gloves and eye protection. You can find a polyester shirt on Amazon for tenbux. I have a bmx helmet.Eye Pro. Gloves. Relatively tight hiking shorts so they won’t get snagged on the seat. Any tech fabric shirt works. I like long sleeves so this time of year I’m alternating between a Patagucci tropical hoody or a super light weight, neon yellow/green $20 motocross jersey if I’m going somewhere with a lot of hikers/other riders. I’m rocking the best helmet money can buy imo (Bell Super Air? Spherical MIPS) because I’m dumb enough already along with knee/elbow pads every ride because at 50 I’m doing stupid sh!t like learning how to wheelie, manual, and bunny hop while trail riding.
Finally, real flat pedal shoes (5.10 Freerider) are so worth it.
If you're going to get airborne pads are not a bad idea.
