General Questions

Where can I test ride a PUBLIC BionX bike?
If you’re in the Bay Area, you can test ride a PUBLIC BionX bike in our Hayes Valley store in San Francisco. We have several PUBLIC bikes outfitted with BionX to try out. Learn about our E-Bike Loaner Program.

Can I get my BionX equipped PUBLIC with matching rims?
BionX motorized wheels are currently available with black rims or silver rims only.

Can I get a BionX electric kit installed on my existing bike?

If your bike is a PUBLIC M8i or PUBLIC D8i
Our PUBLIC M7i and PUBLIC D8i - and older 8-speed internally geared PUBLIC bike models - feature our highest quality chromoly steel frame. This more durable steel frame has the strength to handle the heavier load of the BionX kit and demands of electric pedal assist. If you own a qualifying PUBLIC bike, we will provide a free evaluation of its condition and a cost estimate for electric conversion prior to any BionX installation.

If you have another brand of bike
We do not install BionX on other bikes besides our PUBLIC M7i or PUBLIC D8i.


Technical Questions

How far can I go on a single charge?
Real world mileage will vary depending on level of assist and terrain. A realistic range for the BionX 350HT M system is 15 - 20 miles, with a maximum range of 37 miles (under minimal assist with ideal conditions)

How fast does the BionX equipped PUBLIC bike go?
By law the BionX kit can only assist up to 20 miles per hour. Also the level of power assist you choose will affect your speed.

How much does it weigh?
The BionX kit adds around 17 pounds depending on the model. Our PUBLIC M7i or PUBLIC D8i weigh about 30 lbs, so a complete PUBLIC BionX bike will weigh around 45 lbs.

How long does the battery last?
Your battery will last up to 600-800 full charges. We recommend charging overnight after daily use. That way you have a full charge each day. It’s okay to keep the battery plugged into the charger for long periods of time.

How will I know when it's time to charge my BionX?
An LCD charge indicator enables you to see battery power levels.

What are the specifications of the BionX kit that PUBLIC installs on your bikes?

PL 350 HT RR M - Range: 60km (37 mi.); Battery: Li-Ion / 37V / 6.4 Ah / 237 Wh; Torque (Nom./Max.): 9/40Nm (6.6/29.5 lb.-ft.); Weight (System): 9.3kg (20.5 lb.); Assist Levels: 35, 75, 150, 300%

Where is the BionX system manufactured?
The BionX system was created and has been manufactured in Quebec, Canada since 1998.


Ownership Questions

How safe are these bikes?
We’ve been riding these bikes for awhile now. You should ride these bikes with the same common sense riding behavior as you would on a normal pedal powered bike. The BionX kit adds significant weight on the rear rack so we’ve found that it takes some getting used to maneuvering the bike when locking. But when you’re riding, the bike feels like you’re gliding.

How should I securely lock this bike?
First, we highly recommend you securely lock this bike indoors and out and about. In fact, we recommend using several locks – one or two u-locks and chains, plus even a cable. 

Can I ride my BionX equipped PUBLIC in the rain?
Yes, the BionX kit is fully sealed and can be ridden in the rain. To prevent corrosion all bikes are best stored indoors.

Do I need a driver's license, registration, or insurance to ride my BionX powered bike?
No license, registration or insurance is required since the maximum speed tops at 20 mph. Simply obey current bicycle laws in your community.

Can I carry the PUBLIC BionX bike in my car or vehicle bike rack?
Check with your rack manufacturer about the maximum weight your rack can carry. Many bike racks are designed to carry several bikes so many of them should be able to carry one heavier electric bike.

What kind of maintenance does this bike require?
Maintenance should be very minimal. Standard bicycle maintenance should be expected; however, the motor and battery should need no maintenance.

Does the BionX system require much maintenance?
The BionX system is equipped with a gear and brushless electric motor that doesn’t require any maintenance. Before being stored for a long period (i.e. winter), the battery should be fully recharged and then should be recharged at least once every 3 months. Please also follow the instructions in the User Guide regarding the proper storage of batteries. Like all bicycles, your BionX equipped PUBLIC should be regularly serviced by a qualified bike shop, at least once a year.

What is the warranty on the BionX system?
The BionX warranty covers a two year period for all parts of the BionX kit for the original owner. Certain conditions do apply. Please refer to the BionX manual for further information.


Delivery Questions

How much does it cost to ship my PUBLIC BionX bike?
It costs $135 to ship your bike to anywhere in the continental USA. We don’t ship outside the USA or Hawaii or Alaska. The battery will be shipped separately for an additional cost.

Once I place an order, how long does it take until I receive a PUBLIC BionX bike?
The expected turnaround is two weeks, depending on stock availability and demand.

What is your return policy?
We have a 30-day guarantee policy. You are responsible for the cost to ship the bike back. If there any scratches or defects on the bike from your use, we will deduct from a full refund based on the quality of the returned bike.
