THE TESTER

MBUK and BikeRadar’s tech writer tested these bikes on everything from swooping singletrack to rocky DH runs, plus some steep and technical ascents that simply aren’t ridable without electrical assistance. Seb is obsessive about set-up, so each bike was fettled to get the best out of it. They were then tested back to back on identical tracks to highlight the di erences in performance. MBUK/BR tech ed Tom Marvin rode all four bikes too, providing a valuable second opinion.
