Battery, range and charging

Altis Sigma: 97.2V 35Ah, Samsung 50S cells, 3,402 Wh. No range figure on the page we read. Charging: About 2 hours from 20% to 80%.

E Ride Pro SR: 72V 50Ah, 3,600 Wh. Range: 62 miles at 25 mph, up to 100 miles at 15 mph. Charging: About 3.5 hours from 20% to 90%.

Seat height: 35 in for the Altis Sigma, 33.5 in for the E Ride Pro SR. Max rider weight: not stated and 302 lbs.

Road: Off-road electric dirt bike For the E Ride Pro SR: Off-road only, per the dealer page. Road rules for electric dirt bikes vary by state.

The catch with each

Altis Sigma: No warranty term on the Voro or REV pages we read, and a younger brand than Sur-Ron or Talaria. At 198 lb and 35 inches of seat it's also a big bike for a newcomer.

E Ride Pro SR: We couldn't find a warranty term on the product pages, and 25 kW in a light chassis is a lot. If you're still learning throttle control, the SS 4.0 makes more sense.
