Bonnell 775 MX Electric Mountain Bike

Description

The Bonnell 775 MX is an electric mountain bike engineered with 6,000 watts of peak power, a 65V 1,300Wh battery, and a design that bridges the gap between downhill MTB and lightweight dirt bikes. At $5,495 USD, it delivers moto-like torque with MTB agility in a 75-pound package. Although not street legal in MX trim, it's one of the most exciting mid-weight electric platforms for private trails, OHV parks, and gravity riders in 2025.

What is the Bonnell 775 MX?

The Bonnell 775 MX is part of Bonnell’s 775 platform, which comes in three versions:

• 775 AM (All-Mountain) – Street legal, lower-power option.
• 775 AM Touring – Adventure touring variation with longer-range balance.
• 775 MX (Moto Cross) – The flagship high-power build designed for off-road only, built for riders who want downhill-bike handling with dirt-bike-level torque.

The MX sits at the extreme performance end, featuring a CYC X1 Pro Gen 4 mid-drive motor paired with a full twist throttle, producing a real-world riding experience closer to a small dirt bike than a commuter e-bike.

Ride Experience

The Bonnell 775 MX is engineered for aggressive trail riders who want to clear jumps, power through climbs, and accelerate like a motocross bike without losing the agility of a mountain bike. At 75 pounds, it is far lighter than e-motos such as the Sur-Ron or Talaria (110–140 lbs), giving it a more playful, poppy ride feel.

It rewards active riding—manuals, whips, and flow-based lines—while providing sustained torque for steep climbs and fast exits. Riders coming from MTB backgrounds adapt quickly, while motocross riders find it a lighter, more flickable alternative.

Battery & Range

The 65V, 1,300Wh pack provides a blend of voltage headroom and usable capacity, translating into reliable torque with less voltage sag during long rides.

• Conservative riding (mixed pedal + throttle): 30–37 miles
• Aggressive throttle-heavy rides: 20–25 miles
• Sustained climbs or sand: Expect less than 20 miles

The aluminum-cased pack aids heat dissipation and durability, making it suited for repeated laps in hot or hilly terrain.

Power Delivery & Tuning

The 6,000W peak output makes the MX a true off-road beast. Riders can fine-tune gearing via sprocket swaps:

• 22T / 24T: Strong low-end torque, ideal for technical climbs.
• 26T / 28T: Offers higher top speed, making it better suited for open terrain.

The throttle-based control system makes it easy to transition from pedal assist to full moto-style riding.

Suspension & Handling

The frame is designed around long-travel MTB geometry, giving the MX a downhill-inspired ride. Suspension and tires should be tuned to the rider’s weight and preferred terrain. Brakes need regular attention due to the heat generated from high-speed descents combined with motorized acceleration.

• U.S. price:$5,495 USD
• Available in batch drops (sizes M–XL) with rotating colorways.
• Expansion to international markets is expected, including Canada and Australia.

10 Frequently Asked Questions (FAQs)

1. Is the Bonnell 775 MX street-legal?

2. How much does the Bonnell 775 MX cost?
The launch price is $5,495 USD in the U.S. market. Pricing may vary by region and dealer.

3. What is the real-world range?
Expect 20–37 miles, depending on rider weight, terrain, gearing, and throttle use.

4. How does it compare to a Sur-Ron or Talaria?
The MX is lighter (~75 lbs), more playful, and MTB-like in handling. Sur-Ron/Talaria are heavier, more planted, and moto-oriented.

5. What battery does it use?
It uses a 65V, 1,300Wh A65-series pack with aluminum casing and dual safety layers.

6. Can the drivetrain be tuned?
Yes. Riders can swap sprockets (22T, 24T, 26T, 28T) to emphasize torque or top speed.

7. Who is the ideal rider for the 775 MX?
Aggressive MTB or downhill riders with private trail or OHV park access who want moto-like performance in a lighter platform.

8. What protective gear is recommended?
At minimum: full-face helmet, gloves, pads, and protective shoes. Treat it like a moto-capable machine.

9. What sizes are available?
Medium, Large, and Extra Large. Riders should size based on terrain preference—smaller for jump play, larger for high-speed stability.

10. How does maintenance compare to normal e-MTBs?
Expect more chain, sprocket, and brake wear due to high torque and weight. Regular drivetrain cleaning, brake pad checks, and tire inspections are essential.

Final Verdict

The Bonnell 775 MX Electric Mountain Bike is not built for casual riders—it’s a purpose-designed, high-performance machine for those who want the thrill of motocross in a lighter, more agile MTB-inspired package. At $5,495 USD, it offers serious value for riders who have the terrain and skill to unlock its potential.

If you need compliance or daily street use, the 775 AM trims are more practical. But for dedicated off-road riders who want one of the most exciting “bridge” platforms of 2025, the 775 MX delivers moto-level smiles with mountain bike soul.
