Sur-Ron Light Bee S VS Altis Sigma
Quick Verdict
The Rundown
Comparing the Light Bee S to the Altis Sigma is like comparing a golf cart to a sports car. The Sigma produces 22kW versus 2.9kW — 7.6x more power. It hits 64 mph versus 31 mph, carries 3402Wh versus 960Wh, and supports 300 lb riders versus 165 lbs. The Light Bee S has two things going for it: 108 lbs and $2,500. These aren't competitors — they exist in different product universes. Someone shopping for a Light Bee S is not cross-shopping a Sigma, and vice versa.

Key Differences
Power & Speed
Sur-Ron Light Bee S
2.9kW peak, 31 mph — gentle, manageable power
Altis Sigma
22kW peak, 64 mph — 7.6x more power
This is the largest power gap in any comparison on this site. The Sigma produces 7.6x more power and is 33 mph faster. The Light Bee S is a neighborhood cruiser; the Sigma is a high-performance electric motorcycle. There is no scenario where the Light Bee S keeps up with the Sigma on any terrain.
Range & Battery
Sur-Ron Light Bee S
960Wh battery, 34-40 miles — efficient for its output
Altis Sigma
3402Wh battery, 40-70 miles — 3.5x more capacity
The Sigma carries 3.5x the battery and delivers significantly better range despite producing 7.6x more power. The Light Bee S's 960Wh battery handles short loops. The Sigma's 3402Wh powers all-day riding. There's no comparison in endurance capability.
Weight & Handling
Sur-Ron Light Bee S
108 lbs — 86 lbs lighter, the lightest in the entire category
Altis Sigma
194 lbs — heavy but stable at speed with planted feel
86 lbs is an enormous weight difference — the Light Bee S could gain an entire extra battery and still be lighter than the Sigma. At 108 lbs, anyone can handle the Light Bee S. The Sigma at 194 lbs requires physical strength to manage off the bike. This is the one category where the Light Bee S wins definitively.
Ownership & Value
Sur-Ron Light Bee S
$2,500-$2,799 — lowest entry cost in the category
Altis Sigma
$5,299-$5,899 — flagship performance justifies premium
The Light Bee S costs less than half the Sigma. But the Sigma delivers 7.6x the performance — you get nearly 8x more power for roughly 2x the price. The Sigma has the better performance-per-dollar ratio. The Light Bee S has the lower total outlay. Neither includes Send Bikes dealer warranty or financing.
The Bottom Line
Our Verdict: It Depends
These are not comparable bikes. The Light Bee S is an entry-level platform for beginners and youth. The Sigma is a high-performance machine for experienced riders. Cross-shopping these makes no sense.
Sur-Ron Light Bee S
Get the Light Bee S if you need the absolute cheapest and lightest electric bike for a beginner, youth rider, or casual neighborhood use.
Altis Sigma
Get the Altis Sigma if you want serious power, serious speed, and a machine built for aggressive riding by adult riders up to 300 lbs.
Send Bikes Alternative
The SS 3.0 sits perfectly between these extremes — 15.8kW, 62 mph, belt drive, and a U.S. dealer warranty for $4,999.
Service & Warranty
Neither the Light Bee S nor the Altis Sigma includes Send Bikes dealer support. Sur-Ron has a more established service network. Altis is newer with developing dealer infrastructure.
Financing & Ownership
Neither bike is available through Send Bikes financing. Send Bikes offers Terrace Finance on models from $4,999 to $5,699, all with belt drive, factory warranty, and dealer support — bridging the gap between these two extremes.
