The Elite Novo Force roller trainer is suitable for bikes with a rim width of 24" to 29". E-mountain bikes with these rim widths may be compatible, but suitability also depends on the specific axle type and width. The trainer is compatible with bikes that use a 5 mm diameter axle and a 130-135 x 5 mm quick release axle. If your e-mountain bike fulfils these specifications, it may be suitable.
