Key Differences
Power & Speed
Sur-Ron Light Bee X
6kW is manageable and forgiving — great for learning and technical trail riding where throttle control matters
Altis Sigma
22kW is 3.7x more powerful with 64mph top speed — this is motorcycle-level performance from an electric platform
The power gap here is enormous. The Sigma produces 22kW — enough to embarrass most 250cc gas dirt bikes. The LBX feels like a toy in comparison. If performance is what you're after, the Sigma is in a different universe.
Range & Battery
Sur-Ron Light Bee X
2400Wh battery charges faster and is cheaper to replace — adequate for 25-40 miles of trail riding
Altis Sigma
3402Wh battery delivers 40-70 miles even at higher speeds — 42% more capacity than the LBX
The Sigma's larger battery provides more range at higher power levels. Even riding aggressively, you'll get 40+ miles. The LBX's range drops quickly when you push it hard on trails.
Weight & Handling
Sur-Ron Light Bee X
126lbs is 68lbs lighter — a massive advantage in tight trails, truck loading, and crash recovery
Altis Sigma
194lbs carries more momentum and feels more stable at the Sigma's higher speeds
68lbs is a huge weight difference. The LBX handles like a mountain bike; the Sigma handles like a motorcycle. For technical singletrack and tight trail riding, the LBX's weight advantage is decisive.
Ownership & Value
Sur-Ron Light Bee X
$4,300-$5,000 with the deepest aftermarket — proven investment with strong resale value
Altis Sigma
$5,299-$5,899 for 22kW is exceptional value per kilowatt — more power per dollar than almost any competitor
These serve different buyers. The LBX is a proven value for trail riders. The Sigma is a performance value for riders who want serious power. Dollar-per-kilowatt, the Sigma wins; ecosystem depth, the LBX wins.
The Bottom Line
Our Verdict: It Depends
These bikes serve fundamentally different riders. The Light Bee X is a lightweight trail bike for riders who value agility and aftermarket depth. The Altis Sigma is a high-performance machine for riders who want motorcycle-level power from an electric platform. Neither is wrong — they're just different categories.
Sur-Ron Light Bee X
Choose the Light Bee X if you ride tight trails, want the lightest possible e-moto, value a proven aftermarket ecosystem, and don't need more than 47mph.
Altis Sigma
Choose the Altis Sigma if you want serious power for fire roads, dual-sport riding, or keeping up with gas bikes — and the 68lb weight increase is acceptable for your riding style.
Send Bikes Alternative
The SR delivers 25kW and 70mph — outperforming the Sigma in power and speed — with belt drive reliability and dedicated dealer support at a comparable $5,699 price point.
Service & Warranty
Neither bike comes with Send Bikes dealer support. Sur-Ron has a more established US dealer network. Altis is a newer brand with limited dealer presence — service and parts availability may require more research in your area.
Financing & Ownership
Send Bikes offers financing on comparable models like the SR, which delivers 25kW and 70mph with belt drive and dedicated dealer support — a strong alternative to the Sigma with better ownership infrastructure.
