Specialized Turbo Como 4.0: real range, hills and charging

A 180 lb rider on the Specialized Turbo Como 4.0 at 16 mph with relaxed pedaling over rolling hills (±2%) on pavement can expect about 45 miles per charge (36–54 mi), using 14.3 Wh per mile. That is 50% of the brand's 90 mi claim. That is about 50% of the claim. At full assist with almost no pedaling over hills it drops to about 29 miles. For less money, the Velotric Discover M ($2,499) goes about 51 miles in the same riding.

180 lb, full assist	10 mph	6 mph	4 mph
180 lb, pedaling	12 mph	7 mph	5 mph
