Alright, let’s take a closer look at the Rad Power Bikes RadCity!
The Rad Power Bikes RadCity is a well equipped eCommuter bike that is easy to get on and off with its step-thru frame design that has a low 20″ standover height.
In addition to the step-thru frame, the RadCity is also available in the triangle frame design in 16″ and 19″ frame sizes in this Gun Metal Grey color.
Here is a video from Rad Power Bikes that shows the RadCity in action with some of the different accessory options.
Now let’s take a closer look at the details of the RadCity Step-Thru.
The frame is constructed of 6061 aluminum tubing with some large tubing and extra reinforcing to create a low step-thru area that has a 20″ standover height. The bike is designed to fit a range of rider sizes from 4′-10″ to 6′-2″.
Here is a closer look at the low step-thru area with the new high capacity 48V 14ah lithium battery that is attached to the seat tube. This is a good location for the battery weight because it is low and centered which is good for overall bike handling.
A reinforcing tube adds strength and stiffness to the frame while providing some protection to the battery in the low step-thru area.
The battery lock is on the upper right side of the battery and the bike comes with 2 keys. Once the battery has been unlocked it slides up and off the frame for removal.
At the top of the battery is a charge level indicator that can be activated by pushing the white button on the left. There is also a charge level indicator on the handlebar display.
Here is a look at the battery mount after the battery has been removed. The battery slides up slightly and then off the mount for quick removal. The seat does not need to be removed to remove the battery.
When the battery has been removed the bike weighs 56.9 pounds. The total bike weight with the battery is 64.5 pounds.
The battery can be charged on or off the bike. The battery weights 7.6 pounds. The charger is about the size of a laptop charger and it takes 5 to 6 hours to charge a completely empty battery.
The controller of the eBike drive system is housed just behind the seat tube of the frame and in front of the rear fender.
The headtube of the frame has a substantial reinforcing gusset for connection to the downtube. There are 4 bolts on the front of the headtube that are for the connection of one of the front racks or baskets that Rad Power Bikes offers.
Here is an example of the front rack bolted to the headtube. A small or large basket can be added to the front or rear rack.
Under the headtube reinforcing gusset is where the internal cable routing enters the downtube. Internal cable routing provides a cleaner look and cable protection.
The aluminum rear rack is welded directly to the frame and it has a 60 pound capacity.
The top of the rack has a number of reinforcing tubes as well as bolt connections for a larger platform, basket, or kids seat.
Below is a look at a few of the accessory options for the RadCity.
This is the small basket attached to the rear rack.
And the Thule Yepp kid seat.
And the Fremont pannier bags. All the RadCity accessories can be found here.
The Rad Power Bikes RadCity packs a lot of punch with its 750 watt motor.
This is the 750 watt Shengyi direct drive rear hub motor that provides assist up to 20 mph.
The RadCity is a Class 2 electric bike which is pedal assist and/or throttle up to 20 mph and 750 watts max.
The Shengyi motor has regenerative braking that will provide some charge back to the battery by becoming a generator when the brake levers are engaged. It helps to scrub off some speed while the front and rear brakes still provide the majority of the braking power.
The RadCity comes equipped with a RST suspension fork with 80 mm (3.15″) of travel, preload adjustment, and a lockout option.
The dial on the top of the fork allows you to lockout the fork for a more efficient ride when riding on smoother roads.
The Kenda K-Rad 26″ x 2.3″ tires are used front and rear. These have an efficient road tread pattern with some off road capabilities.
Tektro Aries mechanical disc brake provide the majority of the stopping power with 180 mm rotors. This is the front brake on the RST suspension fork.
And the same Tektro Aries mechanical disc brake with 180mm rotor mounted to the 750 watt Shengyi direct drive rear hub motor.
The handlebars have a swept back design for the easy going cruiser ride style.
You can see in this side view how they are angled back for a comfortable swept back position.
The RadCity comes equipped with an adjustable angle 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 for wrist support, the front Tektro disc brake lever with integrated bell, and the control pad.
Here is a closer look at control pad with the up and down arrows that change the pedal assist levels on the display. The center mode button turns the bike on/off and cycles through information on the display.
The left brake lever (front brake) has an integrated bell that is easy to ring by pulling on the small lever. The front and rear brake levers have sensors that will stop the assist and activate the regenerative braking that recharges the battery while helping to slow the bike down.
Each brake lever has a rubber grip surface that provides a solid grip in wet or dry conditions.
The LCD display is located in the center of the handlebars and provides the following information:
- Battery level
- Odometer & trip distance
- Current speed, average speed, max speed
- Pedal assist level. There are 5 levels of pedal assist. The RadCity uses a cadence sensor for the pedal assist system.
- Watts that the motor is providing
There is a backlit option for riding in low light and it can be turned on by holding the up arrow and mode button on the control pad for a few seconds. That also turns the headlight on.
There is a USB charging port just under the display so that you can charge your smartphone, tablet, or other USB device when you are out and about.
The right side of the handlebar features a faux leather grip with ergonomic shape for wrist support, twist grip throttle, rear Tektro brake lever, and Shimano 7 speed shifter.
The 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.
There are 2 chain guards that keep the chain on the front chainring and they provide some protection to keep your pant legs clean.
A Shimano Acera rear derailleur shifts through the 7 speed Shimano freewheel with a 14 tooth to 34 tooth range. There is also a bash guard to protect the rear derailleur if the bike were to be dropped on the right side.
The Wellgo aluminum pedals have a wide platform with a solid grip surface. There are reflectors on each end of the pedal for extra visibility for riding in the dark.
The Velo Plush seat has a wider profile that matches the comfortable ride style of the RadCity well.
On the back of the seat is a handle to make it easier to pick up and maneuver the bike.
A 300 lumen LED headlight is attached to the front fork and it is powered by the eBike battery. It is turned on by holding the up arrow and center button on the handlebar control pad.
A LED taillight is attached the rear rack and it is powered by 2 AAA batteries that come with the bike. It has flashing and solid light mode options.
Last but not least is the kickstand that is bolted to the chain stay of the frame. The height is adjustable so that you vary the tilt of the bike when it is parked.
