Key Differences
Power & Speed
E Ride Pro SR
25kW peak, 70 mph, 1.8s 0-30 mph
Altis Sigma
22kW peak, 64 mph top speed
The SR holds a 3kW (14%) power advantage and reaches 6 mph higher top speed. Both bikes are seriously fast, but the SR's extra headroom shows on straightaways and climbs. The 1.8s 0-30 mph sprint gives the SR a slight edge off the line. At this price tier, 14% more power matters.
Range & Battery
E Ride Pro SR
62-93 miles on 3600Wh Samsung 50S cells
Altis Sigma
40-70 miles on 3402Wh pack
The SR carries 6% more battery capacity with premium Samsung 50S cells, but the range gap is larger than 6% — up to 93 miles vs 70 miles at best case. The SR's lighter weight and belt drive efficiency contribute to better miles-per-watt-hour. The Samsung 50S cells also maintain capacity longer over years of cycling.
Weight & Handling
E Ride Pro SR
183 lbs with belt drive simplicity
Altis Sigma
194 lbs with aggressive trail geometry
The SR is 11 lbs lighter than the Sigma. Both bikes handle well at trail speed, but the SR's weight advantage compounds with belt drive to deliver a cleaner, lighter-feeling ride. The Sigma's frame geometry is designed for aggressive trail use, which some riders may prefer.
Ownership & Value
E Ride Pro SR
$5,699 with belt drive, Samsung cells, full dealer warranty
Altis Sigma
$5,299-$5,899 with chain drive
The SR and Sigma are priced within striking distance of each other. The SR includes belt drive (zero chain maintenance), Samsung 50S premium cells, and Send Bikes dealer warranty through Central Georgia Powersports. The Sigma uses chain drive that requires regular maintenance. At similar prices, the SR delivers more power, more range, less weight, and lower long-term maintenance cost.
The Bottom Line
Our Pick: E Ride Pro SR
The SR edges the Altis Sigma on every spec — 14% more power, 6 mph faster, better range, lighter weight, belt drive — at a comparable price. The Sigma is a strong bike, but the SR is the better buy.
E Ride Pro SR
Get the SR if you want the best specs-per-dollar under $6K — more power, more range, lighter weight, and belt drive with Send Bikes dealer support.
Altis Sigma
Get the Altis Sigma if you have an Altis dealer nearby, prefer its frame geometry, or find a deal on the $5,299 base configuration.
Service & Warranty
The SR ships with Send Bikes dealer warranty and support through Central Georgia Powersports. Altis Sigma warranty depends on your dealer. Altis is a newer brand with a growing but still limited dealer network — verify service availability in your area before purchasing.
Financing & Ownership
The SR is available through Terrace Finance. Altis financing varies by dealer. At similar monthly payments, the SR includes belt drive that saves $100-200/year in chain maintenance costs. Samsung 50S cells are rated for better long-term capacity retention than standard cells.
