The Yukon 750 is also available in this white color. This particular bike above has a few more accessories than the stock bike comes with.
First of all let’s take a closer look at the frame that is constructed of hydroformed 6061 aluminum tubing.
VoltBike offers 2 different frame sizes:
20″ frame to fit riders in height from 5′-7″ to 6′-4″
17″ frame to fit riders in height from 5′-3″ to 5′-9″
The bike in this review is the 20″ frame size.
A good example of the hydroformed tubing is the top tube that has some rectangular to triangular tube shaping. This adds some style to the frame design as well as some large connections points at the headtube and seat tube.
The top tube has also been sloped down to create more standover height.
In this view you can also see the large downtube that houses the 48V 16ah lithium battery that uses Panasonic cells. This is a good location for the battery because it is low and centered on the bike for more balanced weight distribution which helps with the bike’s handling.
There is internal cable routing in the downtube for cleaner look and cable protection.
Here is a closer look that triangular top tube connection to the seat tube. And below that is the connection of the seat stays to the seat tube. The thick aluminum welds are typical of all the tube connections on the frame.
Here is a closer look at the 48V 16ah lithium battery that is house in the downtube of the frame.
At the top of the battery is the battery level indicator. There is also a battery level indicator on the handlebar display.
On the right side there is a USB charging port (covered by a rubber cover) so that you can charge your phone, tablet, or other USB powered device.
On the left side of the downtube is the battery lock.
Once the battery is unlocked with one of the supplied keys it rotates to the left side of the bike for removal.
This is a view of the downtube with the battery removed. You can see the key in the battery lock (the bike comes with 2 keys) and the battery connection points at the top and bottom of the downtube.
When the battery (9.25 pounds) has been removed the bike weighs 61.0 pounds. The total bike weight with the battery is 70.25 pounds.
Here is a look at the battery removed from the bike with the charger. The charging port is at the bottom left side of the battery and the battery can be charged on or off the bike. It takes 3 to 4 hours to charge a completely empty battery.
Now let’s take a look at the drive system.
This is the Bafang 750 watt (500 watts for the Canadian market) geared rear hub motor that provides assist up to 20 mph. The motor provides up to 80 Nm of torque.
The Yukon 750 is a Class 2 electric bike which is pedal assist and/or throttle up to 20 mph with assist and 750 watts max.
On the left side of the motor is the 180mm disc brake rotor for the rear Tektro Auriga hydraulic disc brake.
Wide Wellgo aluminum platform pedals provide a solid grippy surface. The Prowheel cranks have an outer chainring guard to help with keeping the chain on the chainring and to help with keeping your pant legs clean.
This is the Shimano Acera rear derailleur that shifts through the 7 speed Shimano freewheel with a 14 tooth to 28 tooth range.
There is also a metal guard to protect the rear derailleur if the bike were to be dropped on the right side.
The Mozo FatMan suspension fork provides 90mm (3.5″) of travel while providing plenty of room for clearance of the 4″ wide fat tires and aluminum fender.
On the left side of the fork is a lockout dial so that you can get a more efficient ride on smooth paved roads. The fork is easily unlocked when riding on rough terrain.
Kenda Krusade Sport 26″ x 4″ fat tires are used front and rear. They have an aggressive tread for riding off road and they have a 60tpi thread rating. Fat tires can be run at low tire pressures for improved riding on sand and snow. More on these ride characteristics in Part 2.
Slowing down the Yukon 750 is handled by the Tektro Auriga hydraulic disc brakes with 180mm rotors front and rear.
This is the rear Tektro Auriga hydraulic disc brake mounted to the Bafang 750 watt motor.
Now we will take a closer look at the handlebar control center.
The Yukon 750 comes equipped with an adjustable angle Promax stem so that you can select the ride style that fits you best. It can be adjusted between upright with shorter reach all the way to a more performance style that is lower with longer reach.
On the left side of the handlebar is a faux leather grip with ergonomic shape (wing) for wrist support, the front Tektro Auriga disc brake lever, and the control pad.
The control pad on the left side of the handlebar adjusts the pedal assist levels with the up and down arrows. The center mode button turns the bike on/off and cycles through information on the display.
The LCD display is located in the center of the handlebars and provides the following information:
Odometer & trip distance
Current speed, average speed, max speed
Pedal assist level. There are 9 levels of pedal assist that uses a cadence sensor for the pedal assist system.
There is a backlit option for riding in low light and it can be turned on by holding the up arrow on the control pad for a few seconds. That also turns the headlight and taillight on.
The right side of the handlebar features a faux leather grip with ergonomic shape for wrist support, twist grip throttle, rear Tektro Auriga brake lever, Shimano 7 speed shifter, and a bell with built in compass!
The Shimano shifter has a lower push button that shifts to the smaller cogs for riding in flatter terrain and the upper lever shifts to the large cogs for climbing a hill.
The twist grip throttle can be used on its own (without pedaling) and it can also be used to provide a boost when using the lower pedal assist levels. It has an on/off button that helps to prevent accidental activation and allows you to only use the throttle when you want to.
The reach of the Tektro brake levers can be adjusted to fit your hand with a set screw on the inside of the lever. There are sensors in the brake levers that will stop the assist and activate when the brake levers are engaged.
The Velo Plush seat has a wider profile that provides a comfortable ride.
One of the accessory highlights is the aluminum rear rack that has various attachment points for bags, panniers, and/or baskets.
The top of the rack has a large platform for bags/baskets or for strapping items directly to it. In this view you can also see the full coverage aluminum rear fender.
The tail light attached to the rear rack is powered by the eBike battery so that you don’t need to worry about separate batteries for the light.
The head light also runs off the eBike battery and it produces a good beam of light for seeing and being seen on the road.
Another accessory highlight are the aluminum fenders that are found on the front and back of the Yukon 750. These provide full coverage of the 4″ fat tires and they have a durable look and feel.
The kickstand is bolted to the chain stay of the frame. Its height is adjustable so that you vary the tilt of the bike when it is parked.
The Yukon 750 also comes stock with this helmet. You can specify if a white or black helmet color in medium or large size.
The helmet has comfortable padding with minimal ventilation.
The helmet buckle has a ratcheting system.

Review Note: Each company pays a fee for a review on Electric Bike Report because of the considerable amount of time that it takes to provide an in-depth review of each eBike. A lot of time is spent on the full range test with distance & elevation profile, the wide variety of detailed pictures, in-depth video, and the write up with the specifications, ride characteristics, pros, cons, and overall thoughts. The reviews on Electric Bike Report are focused on providing you with a detailed “virtual” look at each eBike to help you determine if it is the eBike for you or not.
