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%.

Fit, warranty and road status
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.
Warranty: not stated on the page we read (Altis Sigma); not stated on the page we read (E Ride Pro SR).

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.
