The lightweight and confidence-inspiring the Prevelo Alpha Four and Five are sure to provide limitless fun for adventurous riders. Check out our review!
Lightweight frames (24" Alpha Four: 19.9 lb, 26" Alpha Five: 22.0 lb)
Wide gear range (gain ratios 1.79–6.6 for 24", 1.66–5.71 for 26")
Low minimum seat height allowing earlier upgrade to larger wheels
Tubeless-ready rims
Hydraulic disc brakes (Promax)
Aggressive yet confidence-inspiring geometry
Three sharp colorways
Aggressive geometry may feel too aggressive for timid riders
Rims are Presta valve only; Presta tubes harder to find locally
No kickstand included
Does not come with tubeless setup stock
