The verdict
The Sting R MX4 is the Light Bee rival most people end up comparing, and for good reason. REV Rides lists an 8 kW IPM motor, a 60V 45Ah pack made with LG 21700 cells (2,700 Wh), 143 lbs and a 12-month warranty handled through Luna Cycle, for $4,499.99 on November 12, 2026. That is more battery than the Light Bee X we priced, for about $100 less. The catch: it ships speed-limited to 20 mph for legal reasons, and REV showed it unavailable that day.
What we like
- 2,700 Wh LG 21700 battery, more than the Light Bee X we priced
- 8 kW IPM motor, rated at 94% efficiency (dealer)
- 143 lbs, 286 lb max load with gear
- 12-month warranty on frame, hubs, calipers and gearbox
- 12 A charger included
The catch
The dealer says it ships limited to 20 mph to comply with federal, state and local laws, and asks buyers not to bypass it. And it was shown as unavailable at REV Rides on November 12.
Who it is for, who should skip it
Buy it if
- You want the Light Bee experience with more battery
- You value a written 12-month warranty
- You ride tight trails where 143 lbs feels nimble
Skip it if
- You want big-bike power: look at the Komodo or the SS 4.0
- Under-16s: the dealer lists 16 and older
Bigger magnets, bigger battery
The MX4 is Talaria's answer to the Sur-Ron Light Bee X. The dealer's spec sheet lists an Interior Permanent Magnet motor (8 kW) with bigger magnets than the stock Sting, and a 60V 45Ah battery built from LG 21700 5,000 mAh cells: 2,700 Wh. Luna and REV pitch it as a strong base for power upgrades, though they also note that modifications can void the warranty.

Brakes and chassis
Talaria fitted bigger, thicker rotors to match the motor. The factory shock uses a 550 lb/in coil. Weight is 143 lbs, and the maximum load is 130 kg (286 lbs) including gear, a limit the dealer frames as street riding, not hard off-road use.
The 20 mph limit
REV Rides says the MX4 is sold for off-road use only and speed- and power-limited to 20 mph to comply with laws. That's the honest version of the "Talaria top speed" question: the bike as sold is limited, and the dealer asks you not to bypass it.

What's in the box
The bike and a 12 A battery charger (dealer listing).
Getting started
Light assembly, a full charge with the 12 A charger, tire pressure and shock sag. Read the warranty terms before touching the controller: aftermarket controllers can void coverage.
Whatever bike you buy, set the softest mode for the first rides, check every bolt after the first few hours, and keep the battery charged between 20 and 80% when you store it, unless the manual says otherwise.
Hidden costs
Gear, wear parts, and the temptation of power upgrades (which can void the warranty). Warranty service runs through Luna Cycle, per REV.
Plan the total, not the sticker: freight or dealer prep, a full set of gear (helmet, goggles, boots, gloves, armor; see our safety gear guide), a stand, and wear parts. Road rules vary by state; read are electric dirt bikes street legal? before you ride on public roads.
Questions to ask the seller
- When is the MX4 back in stock?
- How does warranty service through Luna Cycle work from my state?
- Which upgrades void the warranty?
- Is the 20 mph limit adjustable for closed-course use?

Alternatives
The three bikes closest in price, and how they differ on the published specs:
Sur-Ron Light Bee X costs $100.01 more ($4,600), carries 660 Wh less battery, is 17.4 lbs lighter (125.6 lbs), doesn't publish a warranty on the pages we read. It scores 8.0/10, below the Talaria Sting R MX4's 8.3, so we'd only pick it for that one strength.
E Ride Pro SS 4.0 costs $499.01 more ($4,999), hits harder (18 kW peak against 8 kW peak), carries 900 Wh more battery, is 18 lbs heavier (161 lbs). It scores 9.2/10, ahead of the Talaria Sting R MX4, so it deserves a look before you decide.
E Ride Pro SR costs $699.01 more ($5,199), hits harder (25 kW peak against 8 kW peak), carries 900 Wh more battery, is 40 lbs heavier (183 lbs). It scores 8.7/10, ahead of the Talaria Sting R MX4, so it deserves a look before you decide.
