Key Differences
Power & Speed
E Ride Pro SS 2.0
12kW peak, 60 mph — strong for the weight class
Altis Sigma
22kW peak, 64 mph — 83% more power
The Altis Sigma has a commanding power advantage — 22kW vs 12kW. That's 83% more peak output. The 4 mph top speed gap is modest, but the Sigma accelerates harder and climbs steeper grades with more authority. For riders who push limits, the Sigma delivers raw capability the SS 2.0 can't match. But consider: the SS 2.0's 86W/lb is competitive with the Sigma's 113W/lb thanks to its lighter frame.
Range & Battery
E Ride Pro SS 2.0
50-90 miles on 2880Wh pack, 2hr fast charge
Altis Sigma
40-70 miles — adequate for aggressive riding
The SS 2.0 delivers 20 more miles at best case despite a similar battery class. Its lighter weight and belt drive efficiency translate to better range per watt-hour. The Sigma's higher power output draws more energy per mile, especially when pushing hard. For full-day trail sessions, the SS 2.0 stretches further.
Weight & Handling
E Ride Pro SS 2.0
139 lbs — light, nimble, easy to load solo
Altis Sigma
194 lbs — heavier but planted at speed
The SS 2.0 is 55 lbs lighter — a massive difference. That's the gap between a bike you toss in a truck bed solo and one that needs a ramp or a second person. On tight trails, the SS 2.0 changes direction faster and fatigues you less on long rides. The Sigma's weight provides stability at high speed but becomes a liability in technical terrain.
Ownership & Value
E Ride Pro SS 2.0
$4,599 with belt drive, warranty, financing
Altis Sigma
$5,299-$5,899 for flagship-level power
The SS 2.0 saves $700-$1,300 upfront plus ongoing chain maintenance costs. Send Bikes includes dealer warranty and Terrace Finance. The Sigma's chain drive adds $200-$400/year in maintenance. If you need the Sigma's 22kW power level, consider looking at the E Ride Pro SS 3.0 or SR — they deliver comparable or superior power at competitive prices with belt drive.
The Bottom Line
Our Verdict: It Depends
Different bikes for different riders. The Altis Sigma has 83% more power for riders who demand peak output. The SS 2.0 is 55 lbs lighter, has more range, belt drive, and costs less. Most riders are better served by the SS 2.0's balance. Power-hungry riders should also look at the SS 3.0 (15.8kW) or SR (25kW) before paying Sigma prices.
E Ride Pro SS 2.0
Get the SS 2.0 if you want the best weight-to-performance balance, more range, belt drive reliability, and dealer warranty — all at a lower price. For more power in the Send Bikes lineup, consider the SS 3.0.
Altis Sigma
Get the Altis Sigma if 22kW of peak power is a must-have and you're comfortable with the 194 lb weight, chain maintenance, and higher price tag.
Service & Warranty
The SS 2.0 ships with Send Bikes dealer warranty through Central Georgia Powersports. Altis is a newer brand — verify warranty terms, parts availability, and dealer proximity before purchasing.
Financing & Ownership
The SS 2.0 is available through Terrace Finance with monthly payments. Altis Sigma financing depends on dealer. Consider the total cost of ownership: SS 2.0's belt drive saves chain maintenance costs, and the lower purchase price means lower monthly payments.
