Key Differences
Power & Speed
E Ride Pro S
6kW peak, 50 mph — efficient and accessible
Altis Sigma
22kW peak, 64 mph — 3.7x more power
The Sigma is in a completely different power class — 3.7x the Pro S's output. That 14 mph speed gap and the acceleration difference are impossible to miss. This is not a close comparison on power. If this power level appeals to you, check the Send Bikes SS 3.0 (15.8kW, $4,999) or SR (25kW, $5,699) — both deliver comparable or better performance with belt drive.
Range & Battery
E Ride Pro S
41-62 miles on efficient 2160Wh pack
Altis Sigma
40-70 miles on larger 3402Wh battery
Similar real-world range despite the Sigma carrying 57% more battery capacity. The Pro S achieves comparable range through its lighter weight and belt drive efficiency. The Pro S charges to 90% in 2 hours versus the Sigma's ~3 hours.
Weight & Handling
E Ride Pro S
136 lbs — 58 lbs lighter, easy to manage
Altis Sigma
194 lbs — heavier but stable at high speed
A 58 lb weight gap is significant. The Pro S is far easier to load, maneuver on tight trails, and recover from. The Sigma's extra weight supports its higher power output and provides stability at 64 mph, but it's a trade-off that matters for everyday handling.
Ownership & Value
E Ride Pro S
$3,999 with belt drive, warranty, and low maintenance
Altis Sigma
$5,299-$5,899 for high-power performance
The Pro S costs up to $1,900 less and includes belt drive (zero chain cost) and dealer warranty. The Sigma uses chain drive that requires regular maintenance. For riders who want Sigma-level power within the Send Bikes ecosystem, the SS 3.0 at $4,999 delivers 15.8kW with belt drive — a better-matched comparison to the Sigma.
The Bottom Line
Our Verdict: It Depends
These are different categories of bike. The Sigma is a high-power machine for aggressive riders. The Pro S is an affordable entry point. If the Sigma's power appeals, the SS 3.0 or SR are better-matched Send Bikes alternatives.
E Ride Pro S
Get the Pro S if you want an affordable, lightweight electric dirt bike that's easy to own and maintain. It's the best entry into the Send Bikes lineup.
Altis Sigma
Get the Altis Sigma if you specifically need 22kW power. But compare the SS 3.0 ($4,999, 15.8kW, belt drive) and SR ($5,699, 25kW, belt drive) first — they offer similar or better performance with lower maintenance.
Service & Warranty
The Pro S ships with Send Bikes dealer warranty and support through Central Georgia Powersports. Altis Sigma service depends on your dealer. The Pro S's belt drive requires zero maintenance versus the Sigma's chain drive.
Financing & Ownership
The Pro S can be financed through Terrace Finance at a much lower monthly payment than the Sigma. If you're considering the Sigma's price range ($5,299-$5,899), the Send Bikes SR at $5,699 delivers 25kW with belt drive and dealer warranty — a strong alternative.
