The Bike Cave Verdict
Ben's Take
On paper the Mars 3.0 is a lot of bike for $1,099 — a genuine full-suspension folder with a Horst-link rear end, a 750W/1400W-peak hub, Shimano 8-speed, NFC start and a 440 lb payload, all folding down in about ten seconds. Fat 20-inch tyres and hydraulic brakes round it out. I haven't ridden this one on camera yet, so treat the score as pending, but as a do-everything folding fat bike it looks like strong value. Full ride review to come.
