RadCity FAQs


What is the distance I can go on a single charge?

The high capacity 48 volt battery will propel you at full speed for 20-25 miles or much further at a slightly reduced speeds. There are many variables that effect exactly how far you will be able to travel on a single charge like wind, hills, payload, and speed. We get an average range of 30 miles in commute/urban environments and 20 miles with really heavy loads and steep hills.

How fast does it go?

The RadCity has a top speed of 20 MPH without pedaling. The 48 volt battery pack and direct drive motor means you go from 0-20 MPH rapidly but the bike is limited to a 20 MPH top speed, which is the legal limit in most locations for use on road. 

How much power does it have?

The RadCity has 750 watts of power on demand. The LCD meter provides a continuous display of power consumption while you are riding. 

How do you control the motor?

The RadCity is equipped with both a throttle and a pedal sensor. You can use either system to control the speed of the electric motor. If you want to cruise without pedaling the twist throttle can be used or if you enjoy pedaling and want to feel more like you are riding a regular bike (with an awesome silent electric motor) you can use the pedal sensor by entering one of the 5 levels of pedal assist.

What is pedal assist, how does it work and why does the RadCity have it?

Pedal assist uses a cadence sensor built into the drive train of the ebike which reads when you are pedaling and automatically turns the electric motor on to provide assistance when you are pedaling. Start pedaling and the sensor tells the motor to turn on. You can adjust the level of assistance with the LCD screen from 1 (lowest amount of assistance) to 5 (highest amount of assistance) to match your desired speed. Since you are pedaling, using the RadCity in pedal assist mode will generally result in a longer range compared to throttle only mode. 

How many charges will my battery last for?

RadCity’s Panasonic lithium-ion battery cells will provide approximately 800 “full” charge cycles before a replacement is recommended. A full cycle is considered one complete discharge, so if you only discharge the battery halfway before recharging normally, your battery will last for twice as many trips! You can discharge the battery 50% and charge it back up to 100% twice to equal one complete charge cycle. 

Does the battery have a memory effect?

No, the battery has no memory effect unlike other battery chemistries meaning you can charge your battery after each and every use, even if you just take a spin down the block. The battery is completely self-managing and the charger stops automatically when the battery is fully charged.

How long does it take to charge the battery?

On average the battery takes 2-4 hours to charge with the included 2 amp charger, but that time is cut in half on shorter trips where you only partially discharge the battery pack. If you fully discharge the battery pack it can take even longer to charge.

Do I have to pedal?

No. There is both a throttle and a pedal assist system. You can pedal and the electric motor will kick in and provide you with assistance, and there is also a twist throttle that will override the pedal assist and allow you to ride the RadCity more like a motorcycle, only silent! The level of pedal assistance will determine how much boost power the motor provides based on your peddling input. Level 1 will be just a little and level 5 will get you moving like a pro cyclist. The throttle is always 0-100% power depending on how much you twist your wrist!

What colors are available?

The RadCity is available in gunmetal gray.

Does the RadCity have regenerative braking?

Yes! Using a brushless direct drive hub motor allows the RadCity to have regenerative braking enabled as a standard feature which allows the user to slow down when traveling downhill or coming to a stop, and charging the battery in the process.

Is it street legal?

Electric bikes are considered bicycles and can be used in the same way as a pedal only bicycle in most locations, However there are a multitude of localities with restrictions so users must check with local law enforcement to be sure they are riding within the law. One example is NYC which has had a ban on the use of electric bikes.

Since the RadCity uses a 48 volt battery allowing the bike to travel at high speeds when desired, users should take extra care ensuring that they operate within the law and check their local regulations on peak power (normally 750 watts in the U.S.) and top speeds (normally 20 mph in the U.S.).

We will be providing an on/off button on the production bikes to disable the twist grip throttle so customers in locations where e-bikes with throttles are not allowed (some locations in Europe etc) will be able to conform to local regulations. The pedal assist system is still be fully functional when the throttle is disabled.

It is our job as ebikers to obey the rules of the road so please ride responsibly.

How do you turn the RadCity On/Off?

The RadCity turns on once you engage the battery “on” button and hold down the mode button on the handlebars for 2 seconds.

What is the size of the bike?

The RadCity is the first ebike from Rad Power Bikes that comes in two frame sizes! The 16" frame best fits riders from 5'2" - 5'10" and the 20" frame best fits riders from 5'11" - 6'7".

Does it come in a women's specific version?

The RadCity uses a unisex design frame meaning it works well for men and women, but we have found that many women do feel more comfortable on our 16" model.

What is the weight limit?

The weight limit for the RadCity is 275 lbs including rider and extra gear.

Can I put a rear bag on it?

Most off the shelf bike bags, panniers, and cargo bike bags fit just fine, but some may require some modifications and tuning to get fitted.

How steep of a hill can the bike go up?

Hill performance depends on the weight of rider and gear and the steepness of the hill as well as some other factors. The 48 volt 20 amp motor controller surprises everyone we have had test ride the RadCity, but we never recommend going up more than a 15% grade using the motor alone.

What is the lowest and highest the seat sits off the ground?

16" - 31"/39"

20" - 34"/43"

How much does the bike weigh?

The bike weighs 60 lbs out of the box.

How much does the battery pack weigh?

The battery weighs 7.2 pounds.

How many gears does the RadCity have and why does it have gears if it is electric?

The RadCity has a thumb shift Shimano 7 speed gearing system. Although it is an ebike, it is still useful to have gears whenever you decide to pedal while cruising or trying to get more exercise or extend your range. The combination of gearing and the 5 levels of variable pedal assistance from the motor means you can always find the most efficient gear and pedal level to go the distance!

Is there a power usage or battery gauge on the bike? 

Yes, there is a full screen LCD display which displays a battery gauge, speedometer, and much more.

Is there a key/interlock to prevent accidental starting? 

There is no interlock currently. However the throttle will not start until one presses a button to activate the motor.

How do I lock it up and what can I do to help minimize the chance of it being stolen?

The RadCity has some great anti-theft features including a locking battery pack that can either be locked onto the frame or removed and brought inside for charging and safe keeping, a permanently attached LCD display, and rear wheel wheel which is bolted down to the dropouts to reduce the chances of a thief stealing the wheel from the bike. Most standard u-locks and cable locks work fine on the RadCity.

Does it work in the rain?

The components are all water resistant and work very well in wet conditions but you should take care to keep your bike parked indoors whenever possible and in a dry location when in storage. The display, motor, battery pack, and throttle are all designed to operate just fine in a normal drizzle or a soggy wet morning commute in Seattle, but you should always take care to dry off your bike and store it properly between use.


What happens if something breaks on my RadCity?

Our ebikes use standard bicycle components meaning replacement parts can be found at any local bike shop (LBS). All of the electrical components are easily swappable in case you need a replacement, or want to upgrade your battery in coming years. The RadCity is so smart that it’s electrical system will actually tell you what is wrong in the case of an error. The LCD readout displays an error code when a component is at fault allowing you to pinpoint the problem right away!

Does the RadCity have a warranty?

Every bike is covered under our manufacturer's 1-year warranty for the original owner against all manufacturing defects.

Is it possible to replace the batteries?

Yes! The battery can be easily removed and replaced by a turn of a key to unlock the battery allowing you to lift it right off for replacement. Our high quality Panasonic cells should provide years of dependable service but when a replacement, or spare pack is needed, it is as easy as unlock and lift!

How do I replace the tires when they have worn?

The RadCity rims fit standard 26’’ tires and most bike shops carry replacement tires. You are also able to purchase replacement tires directly from Rad Power Bikes.

How do I turn on the headlight?

Once the battery/LCD display are on, hold down the up arrow and mode buttons located on the left side of the handlebars for 2-3 seconds.
