Alright, let’s take a closer look at the Haibike Radius Tour!
The Haibike Radius Tour is a compact eBike for easy maneuverable riding on a tour ride or around town.
The frame is constructed of hyrdoformed 6061 aluminum with a Gravity Casting Interface motor mount that is designed to be lightweight with high strength.
You can see the unique design provides a relatively low step over area in the middle of the frame for an easy get on and ride characteristic.
The 36V 13.6ah 500 Wh Yamaha lithium battery is housed inside the main frame area for centered and low weight distribution. The combination of the centered and low motor and battery is beneficial for the handling of the bike and a balanced feel when picking the bike up.
Here is a closer look at the top tube reinforcement tube to the seat tube. It provides strength and adds some unique style to the Haibike Radius Tour. The hydroformed tubing has some unique shapes that include triangular, rectangular, and the classic round tubes.
In this view you can also see the internal cable routing in the top tube for clean looks and cable protection.
In this view you can see the head tube, top tube, and downtube connection with clean internal cable routing. The battery lock is also seen just beyond the cables.
The front end features a clean looking aluminum fork, 20″ front wheel with Schwable Big Ben tires, and a full coverage SKS fender.
It’s a little hard to see in this view but behind the large 52 tooth chainring is the 500 watt Yamaha PW mid drive motor that provides up to 20 mph of pedal assist. The PW motor provides up to 80 Nm of torque.
The other side of the Yamaha PW offers a better look at this mid drive. It uses 3 sensors to provide the proportional assist: torque, cadence, and wheel speed sensors.
There is a plastic bash guard below the motor.
That’s an interesting looking chain?! It is actually a chainguard cover that goes over the chain to keep your pant legs clean.
This is the Shimano Nexus 8 Speed internally geared rear hub that keeps the drivetrain clean and simple. All of the drivetrain system is housed within the rear hub vs. the typical cogset and rear derailleur.
Here is a closer look at the 36V 13.6ah 500 Wh Yamaha lithium battery. It is removed by unlocking it with the supplied key and sliding the battery to the left side of the bike.
Here is a look at the downtube of the frame with the battery removed. When the battery has been removed the bike weighs 42.65 pounds which makes it a little easier to pick up.
This is a look at the Yamaha lithium battery once it has been removed from the frame with the charger. There is a battery level indicator on the center part of the battery. The battery weighs 6.60 pounds.
The charger is about the size of a laptop charger and it takes about 4 hours to charge a completely empty battery.
The battery can be charged on or off the bike with the included charger.
Schwalbe Big Ben 20″ x 2.15″ balloon style tires are used front and rear. They have an efficient tread pattern with grooves for channeling water and reflective stripes on each side for being seen at night.
The Spanninga Kendo, 15 lux front headlight runs off the eBike battery and it is turned on at the control pad on the handlebar.
Shimano M445 hydraulic disc brakes with 160mm rotors are used front and rear.
Here is a look at the Shimano M445 hydraulic disc brake on the back.
The handlebar controls are pretty simple and straightforward with the large Yamaha display in the center of the bars.
On the left side of the handlebar is the XLC Endorfin lock on grip, Shimano M445 hydraulic disc brake lever, and Yamaha control pad.
The on/off button is on the top side of the control pad, the up and down arrows adjust the pedal assist levels, the S button cycles through the display info, and the light button turns on the lights that are powered by the eBike battery.
There is a walk mode button on the bottom of the control pad but it is not active for US models, just for the European market at this time. There is also a USB port that uses the smaller USB connection for charging some phones or other USB devices.
Here is a closer look at the Yamaha display that is mounted in the center of the handlebar and provides information on the:
The display is removable by holding down the tab at the top and sliding the display up and off.
On the left side of the handlebar is the XLC Endorfin lock on grip, Shimano Nexus 8 speed grip shifter, Shimano M445 hydraulic disc brake lever, and the bell.
The Shimano Nexus 8 speed grip shifter shows your current gear selection in the center window. The Shimano M445 brake levers reach can be adjusted to fit your hand size.
The Speed Lifter Twist is a mechanism that lets you quickly adjust the handlebar height and orientation.
When the quick release lever is opened the handlebar can be raised up to 5.75″ in height. You can also see the “lift the bolt to twist” and when that is done the handlebar can be quickly rotated 90 degrees while keeping the front wheel straight.
This is the stem at full height. The angle of the stem can also be adjusted for additional height that also changes the reach.
Here is a look at the handlebar rotated 90 degrees while keeping the front wheel straight. This is helpful so that the bike can be easily stored in a narrow space in the house, workplace, garage, or cellar. It is also useful for loading into the car or onto the bike rack on the car.
The VP F80 aluminium pedals provide a grippy platform with fold-ability!
These pedals fold by opening the top and bottom of the pedal.
The Haibike seat has a medium width profile and a channeled center section for a comfortable ride.
The aluminum rear rack comes provides a platform to carry bags or baskets. The stated max cargo weight is 55 pounds (25 kg).
The Haibike Radius Tour does come with a Busch & Müller Xeltec rear light that is powered by the eBike battery. This particular test bike did not come equipped with it, there is a reflector in its place.
Here’s a look at the top of the rear rack. There is a spring clip that will hold some items to the top of the rack.
Assist Options: 4pedal assist levels: Eco+, Eco, Standard, High
Speed: Pedal assist up to 20 mph which makes this a Class 1 eBike
Display: Yamaha display that provides information on the battery level, pedal assist level (there are 4 levels), current speed, average speed, max speed, odometer, trip distance, estimated range remaining, pedaling cadence, and current time.
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.
