79Bike Falcon M vs Valtinsu EM-5 Pro: Specs, Support and Real World Value
Short answer: the 79Bike Falcon M wins on battery size and wheel size, while the Valtinsu EM-5 Pro wins on price and on slow, technical trail work. Both are electric dirt bikes for grown riders. The money goes to very different places on each one.
The Falcon M runs a 72V 35Ah LG pack, 19 inch wheels at both ends and a claimed 8,000W peak. The EM-5 Pro is an adult electric off-road motorcycle built around a 60V 5,600W geared motor, 177 lb-ft of torque and a 52 mph top speed. It lists at $1,699.
We wrote this for the adult rider who has a Sur-Ron class bike in one browser tab and something far cheaper in the other. Specs, owner threads on Reddit and each brand's support pages went into it. So did a simple question about every number: does it change anything on dirt?

Which Falcon M are you looking at? Retail listings mix it up with the Falcon Pro all the time. Across the pages we checked, the M usually shows up as 4,000W rated with 8,000W peak and roughly 50 mph, and when we looked in October 2026 the 79Bike store only carried the Falcon Pro (10kW peak, 410 Nm). A seller quoting 10kW for an M is probably describing the wrong bike. Get the controller version in writing. |
Quick Verdict
It splits by where you ride and what you plan to change later.
• Open fire roads and long loops: Falcon M, for the stored energy and the 19 inch wheels.
• Best value for adult trail riding: the EM-5 Pro geared trail bike,
with 52 mph and 177 lb-ft for $1,699.
• Tight singletrack: EM-5 Pro, since a 41.7 inch wheelbase turns in where a 49.2 inch one runs wide.
• Building it up: Falcon M. Forum posts put Sur-Ron Light Bee X parts overlap near 80%.
Specs Side by Side
EM-5 Pro figures come from Valtinsu's current spec sheet. Falcon M figures come from the most consistent published listings, since 79Bike no longer runs a dedicated M page.

Look at the battery row and the price row first. One bike has about 56% more energy. The other is under half the price.
Power and Torque: Peak Watts vs Usable Pull
Peak watts look good on a product page, but torque at the rear tire is what gets you up a hill.
Falcon M: 72V Headroom
Same power, less current. That is the whole trick with 72V, and it keeps the wiring and controller cooler when you hold the throttle open on a wide Colorado fire road for a mile or two at 40 mph. Plenty of 48V and 60V bikes go soft there. The Falcon M mostly does not.
EM-5 Pro: Geared Torque Down Low
Valtinsu went with a geared motor instead. The motor itself spins fast, the gears slow the wheel down, and the torque goes up by roughly the same ratio.
Say you are on a rocky ledge outside Sedona, front wheel up, rear tire stuck against the step, barely moving. Peak power is irrelevant at 3 mph. You want 177 lb-ft that comes in gently when you crack the throttle, and that is the job the gearing does. Valtinsu lists a 45° climb rating and 2,500W continuous.
|
Compare torque carefully Check where it was measured. Some spec sheets list torque at the motor shaft and some list it at the wheel after the gears, which means 410 Nm on one page and 240 N·m on another may not be comparable at all. |
Battery, Range and Charging
The Falcon M takes this section without much argument.
Energy on Board
Roughly 2,520 Wh in the Falcon M. About 1,620 Wh in the EM-5 Pro. You get those by multiplying volts by amp hours, and the 900 Wh gap shows up fastest on long desert loops ridden near 40 mph, because air drag grows with the square of speed.
Range in the Real World
Treat both range claims as best case. Soft Pine Barrens sand, climb after climb, or a 220 lb rider will each knock a big chunk off. Summer adds its own cost. Battery University explains how rising internal resistance makes a pack sag under load, and why lithium cells stored full and hot lose capacity faster. Same story for both bikes.
Charge Time
About 3.5 hours for the Falcon M, 7 to 8 for the EM-5 Pro. Overnight garage charging hides the difference completely, but a rider who wants a second session after lunch will notice it.
Chassis, Wheels and Rider Fit
19/19 vs 17/14 Wheels
Bigger wheels roll over things. On Moab slickrock ledges and deep ruts the Falcon M's 19 inch pair meets each edge at a flatter angle, and the bike feels more like a small motorcycle than a pit bike. The EM-5 Pro runs 17 inch front and 14 inch rear. Lower, shorter, quicker to turn on a tight switchback, and easier to catch when the back steps out.
Size, Weight and Load
At roughly 130 lb the Falcon M is the lighter bike by about 13 lb. The EM-5 Pro answers with a 287 lb max load, above what most Falcon M listings claim, which leaves room for a 200 lb rider in boots, armor and a full hydration pack.
Suspension Setup
On the EM-5 Pro a shock pump sets rear sag for your weight, with no spring to swap. The Falcon M runs Fastace hardware, which plenty of experienced riders already know how to tune. Start from the manual on either bike rather than the pressure it shipped with.
Support, Parts and Ownership
A spec sheet does not help much when a display dies two days before a trip, so we looked at what happens after the sale too.
Falcon M: Sur-Ron Parts Overlap
Owner posts put compatibility with Sur-Ron Light Bee X aftermarket parts at around 80%, which opens up bars, controls and a long list of upgrades. Swingarm, subframe and linkage are different. Check part numbers. The brand is newer than Sur-Ron or Talaria, so high mileage reports are still thin.
EM-5 Pro: Model Specific Support
Valtinsu posts separate EM-5 Pro user manuals and sells model specific replacement parts such as the Pro display and brake levers. A 1 year limited warranty comes with the bike. For a rider who wants to leave it mostly stock, that is less research per repair.
Price and Real World Value
Price changes the picture more than any spec. With no official Falcon M listing to quote, we used the current Falcon Pro price as the Falcon reference.

If the plan is to buy an EM-5 Pro and immediately chase 72V and bigger wheels, the savings disappear and the Falcon is the better start. Most riders stop at tires, bars and suspension tuning. For them the EM-5 Pro stays ahead.

Before your first ride No plates, no public roads. Both bikes belong on private land or designated routes, and the BLM's off highway vehicle page is a good place to find legal public riding, keeping in mind your state's own OHV rules sit on top. Get a helmet with the DOT label NHTSA describes, not a novelty lid. We would also book a Motorcycle Safety Foundation DirtBike School day before anyone tries 50 mph. The EM-5 Pro is for riders 18 and up. |
Conclusion
The Falcon M is the stronger bike on paper, and for fast open riding or a big build its 72V 35Ah pack, 19 inch wheels and Sur-Ron parts overlap are real advantages. Just confirm which version you are buying.
The EM-5 Pro is the easier purchase to defend: 52 mph, 177 lb-ft through a geared motor, an adjustable air shock and factory parts support for $1,699. Most adults spend their trail time between 10 and 30 mph. At those speeds it is the better use of the money.

FAQs
What is the top speed of the 79Bike Falcon M?
About 50 mph. That figure usually sits next to 4,000W rated and 8,000W peak in Falcon M listings; when a page says 55 or 56 mph it is almost always the Falcon Pro. Heavier riders, a half empty pack or loose dirt will all pull it down. Ask the seller for the factory speed setting in writing.
Is 79Bike a good bike brand?
Good hardware, short history. The 72V LG battery, Fastace suspension and light frame hold up well against the class, but the owner record is a few years thinner than Sur-Ron's or Talaria's. Vet the dealer. Ask who handles warranty claims and which parts they stock.
Is the EM-5 Pro faster than the Falcon M?
By about 2 mph on paper, 52 against roughly 50. Hold either bike flat out for several miles and the Falcon M's bigger 72V pack keeps its pace longer. In tight woods neither one gets close to its limit.
What is the weight limit on a 79Bike?
Around 240 lb for the Falcon M in most sources. The current Falcon Pro is listed at 300 lb, and the Valtinsu EM-5 Pro at 287 lb. Step on a scale in your boots, armor and pack, then set sag for that number rather than your bare weight.
What is the best electric dirt bike for off-roading?
That depends on the trail. Open desert and fire roads reward a big battery and big wheels, so the Falcon M fits there. On rocky, slow trails the EM-5 Pro's low speed torque and compact chassis are the better tools. Start from the trail you ride most.
Is the 79Bike Falcon Pro road legal?
Not as sold. In most states a bike with this much power falls outside the low speed electric cycle classes, so the Falcon Pro and the EM-5 Pro both belong on private land and designated off highway routes. Your state DMV and the local land manager have the final word.
How fast is the 79 Falcon?
That depends on which Falcon. The M runs about 50 mph, the current Falcon Pro is listed at 56 mph with a 10kW peak, and the GT sits above both. Match any speed claim to the exact model and model year.
Can a Sur-Ron go 70 mph?
Not stock. Most sources put the Light Bee X near 47 mph, and the riders posting 70 mph runs have changed the battery and controller, with knock on effects for warranty and reliability. A 72V bike starts higher from the factory.
