Overview

500W Power / 160Nm Torque

Would you like a little more? The M620 motor with 500 watts rated power, 160Nm of torque, just 5.3kg - always delivers top performance and is the first choice for electric cargo and modern eMTBs. With its triple sensor system (1 torque, 2 speed sensors) it reacts with lightning speed to your pedal-power input and delivers impressive support at all times. Voltbike Yukon Core is using mid-drive motor Bafang M620 48v 500w.

Samsung Battery

VoltBike Yukon Core is using 48v 19.2Ah (921Wh) battery pack with Samsung INR18650-35E cells. Samsung SDI’s superb cell balance technology contributes to the uniform quality of the packs and driving units, and ultimately to the quality of the e-bike. Samsung SDI’s Li-ion battery cells are preferred by high-end e-bike makers and companies that lead the e-bike market.

Extra Smooth Ride

Voltbike Yukon Cores comes standard with lockout suspension RST Guide which can handle up to 4.8 inch tire. Designed for quick release axles and bolt on axles for ease of use. 135mm dropout, 32mm stanchions, 210mm steerer tube, 90mm travel. Weighing a remarkable 7 lbs., this fork is ready to tackle anything you throw at it.

Sturdy Rear Rack

Standard for Yukon Core is aluminum rear rack with extra wide tubing. Rated for up to 50lbs of cargo this rack can fit any load with ease. Mounted directly on the rack is LED rear taillight with brake light functionality.

Puncture Resistant Fat Tire

Fat tire bikes provide improved grip and traction on the most troublesome terrain by adding extra contact surface. Yukon Cores comes with puncture resistant tires Kenda Juggernaut K-Shield. Reflective liners are adding extra visibility at night.

LCD Screen

Large practical display located in the middle of the handlebar offers real time stats such as speed, pedal assist level, battery capacity, distance traveled and current load. You can also charge your cell phone through the built-in USB connector. New for the display is the lighting sensor which atomically activates your lights when it gets dark.

SRAM X5 9 Speed

The SRAM X5 rear derailleur provides incredible shifting speed and precision EXACT ACTUATION™ technology eliminates slop and shifting variation. The actuation remains accurate and smooth, effortlessly navigating through mud, rebounding off rocks, no matter where you are or what conditions you encounter.

Simple Controls

Our redesigned cockpit includes large easy to read LCD screen which shows all the important information like speed, battery level and current load. Get instant power with the integrated thumb throttle.

Always Visible

Yukon is equipped with a high lumen front LED light with a consistent, well-focused beam pattern. Rear LED light powered using the main battery pack. Features brake light functionality that is activated any time the brakes are applied. Reflective tire liner ensures you are visible from the side.

Extremely Customizable

Fit & Size

  • Fit Guidelines

    Choosing the right frame size is essential for ensuring comfort on your new bike, and the simplest way to approach this is by measuring your inseam. Your inseam is measured from the middle of your crotch down to your ankle bone on either leg.

    Suitable inseam range:

    < 29"     74cm
    30" 76cm
    32" 81cm
    46" 117cm
    48" 122cm
    > 49" 124cm

    Great fit with plenty of room for seat height adjustment.

    Good fit but potentially limited seat height adjustment or top tube clearence.

    Poor fit, frame is either too big or too small.

Frequently asked questions

Some questions and answers are automatically generated.

How does the mid-drive compare to hub-drive?
Many reviewers with prior hub-drive experience note that mid-drive delivers a more natural riding sensation and better hill-climbing ability. The mid-drive motor works with the bike's gears, allowing flexible power delivery across different terrain, whereas hub-drive cannot shift gears. Reviewers report the transition requires getting used to, but most find it superior for hills and varied terrain.
Can it handle steep hills and challenging terrain?
Yes. Reviewers consistently praise the hill-climbing ability, with one noting it "will claw its way uphill" and another describing it as climbing "damn near anything" even at lower assist levels. Several reviewers confirm it performs well on gravel, trails, loose sand, and snow with appropriate tire upgrades.
How far does the battery last on a charge?
Reviewers report varying real-world range depending on terrain and assist level. One rider completed a 20 km loop in soft snow with 600 meters of elevation gain and returned with battery to spare. Another covered over 200 km in three weeks of regular riding. The on-screen range estimate can be unreliable, especially during climbs, so reviewers recommend interpreting it carefully rather than relying on it as a precise indicator.
Is the bike comfortable for longer rides?
Most reviewers appreciate the upright riding posture and note comfort, especially with optional suspension seat upgrades. One rider with 40 years away from cycling found the geometry excellent. However, several note the bike is heavy (around 80 pounds) and requires strength when mounting, dismounting, or moving it off-bike—reviewers suggest this is less of an issue during riding due to motor assist.
What is the learning curve with the M620 motor?
Reviewers note you need to shift gears thoughtfully, similar to driving a manual transmission car, because the motor's high torque can damage the chain with improper shifting. Several mention a brief "gear whine" at lower speeds and a momentary motor cutoff during shifts (which is intentional to protect the drivetrain). Once accustomed to these traits, reviewers report riding "all smiles."
Are the included brakes adequate for steep hills?
Reviewers confirm the hydraulic brakes work well and stop the bike easily. However, a couple of riders mentioned consideration of upgrading to larger rotor sizes or 4-piston brakes for additional braking power on very steep terrain, suggesting the stock brakes are adequate but may have room for enhancement in extreme conditions.
How fast can it go?
Reviewers report speeds around 50 km/h on pavement, with one describing it as "VERY fast." Speed depends on assist level, terrain, and rider input, but multiple owners note it performs impressively well for acceleration and sustained speed.
Is it good for winter riding?
The Yukon Core can handle winter conditions, though reviewers who do serious winter riding recommend upgrading to studded tires. The stock tires offer "okay" performance on packed snow but lack traction on ice and slippery packed snow. Several owners have added studded tires (like 26x4.8 size) and report improved winter capability.
How is the component quality at this price?
Reviewers consistently describe the components as lower-end or mid-level but functional and good value for the price. The SRAM X5 rear derailleur, hydraulic brakes, and stock seat are described as adequate but upgradeable. Several owners mention planning component upgrades (better derailleurs, seats, handlebars) but most agree the overall package offers excellent value compared to competitors.
Does the display show accurate information?
The LCD display is described as bright and easy to use, with most information reliable. However, the on-screen battery range estimate is noted as inaccurate and can drop dramatically during hill climbs without reflecting actual battery depletion, requiring riders to interpret it contextually rather than trust it absolutely.
