Frequently Asked Questions


How it Works

How Does PedalCell Work?

PedalCell consists of two pieces. The Generator attaches to your bike's frame, on the front or back, and touches the rim. When your wheel spins, the side of the rim spins the Generator to create electricity. This electricity is sent up a cable to the second part of the device: the Smart Power Hub with two USB-C charging ports. The Smart Power Hub uses our patented CadenceX technology to stabilize and temporarily store the power coming from the Generator. If you speed up, slow down, or even stop for as long as 30 seconds the power hub will provide power to your devices.

TLDR: Unlimited Power!

Can PedalCell work on anything besides bicycles?

PedalCell's electronics and generator can be used on any rotating surface with proper mounting and alignment. PedalCell's warranty only applies to bicycle mounting. Our support team is equipped to only help with bicycle-related questions.

Installation & Compatibility

Is my bicycle (or trike) compatible with PedalCell?

PedalCell is compatible with the majority of bicycles and delta trikes with front forks equal to or smaller than a 1″ X 2″ oval, including disc, drum, and rim/caliper/cantilever brake setups. As a rule of thumb, we do not recommend PedalCell be mounted on extreme road/aero/competition bikes or heavy suspension mountain bikes due to their unusual/large fork geometries. In addition, we do not recommend mounting with carbon rims due to their limited heat dissipation and willingness to handle force on the rim face.

PedalCell also supports mounting on the rear seat/chainstays of Tadpole Trikes and bicycles. Those directions can be viewed on our install page.

Does PedalCell work with fork suspensions?

PedalCell works with the majority of bicycle fork suspensions with a few exceptions.

In the case of exceptions, riders can mount on the rear seatstays and chainstays. Exceptions primarily include fork suspensions with an outer chassis that moves relative to the rim such as:

Lauf Suspensions

Trust Performance Suspensions

Cannondale Lefty Suspensions

Inverted Fork Suspensions

How much space does my rim need?

PedalCell can work on most non-carbon rims, including those that do not have braking surfaces. The O-Ring needs approximately 4.7mm of contact area on a rim. This is about <1/2 the surface area needed by most rim brake pads.

Can PedalCell be mounted in the rear?

PedalCell supports mounting on the rear rim via the chainstays and seat stays of Tadpole Trikes and bicycles. Install directions can be viewed on our install page. Seat stays of sufficient size can be mounted as well. See below:

 

How long do the O-Rings last

PedalCell's O-ring is custom-specced to balance performance with long-term durability. It is recommended to swap every ~2-3,000 miles. Additional O-Rings can be bought separately or included in the Ultimate Bundle on the PedalCell store.

Does my wheel need to spin exactly true?

No, PedalCell's spring adjusts the generator’s position to maintain optimal contact on rims that do not spin exactly true.

Is PedalCell theft-resistant?

The included hex bolts should deter most thieves from stealing your PedalCell (no more difficult to steal than your caliper brakes or handlebars). However, we do sell a security bolt kit in our store for riders who want extra peace of mind when parking their bicycle outdoors for extended periods. This kit is included with our Ultimate Bundles.

Does PedalCell work with fork mounts/panniers?

Yes, PedalCell works with most fork mounts/panniers.

Does PedalCell require maintenance?

We recommend the replacement of the O-Ring (sold in store) every 2-3K miles. Riders should pay attention to PedalCell's mounting on the bicycle rim before and after every ride to ensure that the device is properly aligned. We recommend re-tightening/adjusting the front fork clamp at least once a month (or more if ridden heavily) to maintain ideal performance.

What lights are recommended?

PedalCell can power nearly any light that is USB powered. For the best experience, we recommend that riders use USB battery-powered lights with "pass-through" charging; the ability to use the light while it's being charged. We compiled a list of of 30+ light options at: pedalcell.com/lights

USB lights without an integrated battery can be used as well. These lights are typically made to be powered by a battery pack. Thus, we advise riders use an intermediately battery pack between these lights and PedalCell. A battery pack with "pass-through" charging capability is recommended.

What types of cables should I use?

Use the original cable provided with your USB device for the best performance. PedalCell includes a USB A-C adapter in the box for devices that do not have a Type-C cable. We also sell low-profile USB cables with UV/splash resistance on our store for a more tangle-free experience.

Which battery packs work best?

PedalCell can charge nearly any USB battery pack. For the best experience, we recommend that riders use batteries with "pass-through" charging; the ability to use the battery while it's being charged. We wrote a blog post on the pros and cons of pass-through batteries here. Batteries that support charging over USB-C 5V/3A charging port tend to charge the fastest from PedalCell.

Can PedalCell be used on an electric bicycle (eBike)? How about charging my eBike battery?

Yes, PedalCell can be used to charge USB devices on any eBike that is compatible with PedalCell's install criteria. However, PedalCell is not made to charge an eBike's battery due to underlying technical (and physics-related) hurdles.

I want to mount PedalCell, even though my bike doesn't meet your install criteria. Can I still try to mount PedalCell there?

We designed PedalCell to work reliably in its original mounting locations. Mounting on any non-supported locations/bikes/trikes can cause unintended performance, durability, and other issues with PedalCell and your other gear. PedalCell is not responsible for any damage resulting from misuse. Read our terms and conditions for more information.

Technology

Is PedalCell water-proof?

PedalCell is validated to survive the outdoors as "weather-resistant" with 11 anti-moisture seals to protect against rain, sleet, snow, etc. We've tested our device under pressurized water and brutal midwestern winters to verify this claim.

Why we don't use the term "water-proof": Riders must prevent liquid from being in the Smart Power Hub's ports while powered-on. While water will not enter inside the device, the liquid can corrode the port's pins while the device is powered on. This is a limitation of all USB ports and is not a limitation specific to PedalCell. Our rubber USB-C plugs help prevent this from happening, however, a simple shake of the Power Hub and waiting until it dries can get water to leave. Using the Power Hub in a bag or pointing downward usually makes this a non-issue. As a general rule of thumb, do not allow water to enter the USB port.

We encourage riders to stay mindful while using their electronics (such as your smartphone or lights) in poor conditions.

Does PedalCell add drag?

As with any bicycle generator, PedalCell does add drag. While there is no such thing as free power, we designed multiple features to ensure noticeable drag is minimal to non-existent to users.

1) High-Efficiency: PedalCell's mechanical-to- USB output is validated by a 3rd party to have a class-leading peak efficiency of 70%. Read about these tests here.

2) Dynamic output: PedalCell only provides the power your devices need. For example, if your phone is almost fully charged with the screen off, our product will output a smaller amount of power.

3) 3W lock: PedalCell's Prioritized port locks max output at 3W for power-conscious riders.

4) Speed-based Output: We dynamically adjust our power at different speeds. For example, we don't deliver 20W at 8 km/h. This curve lowers the chance of noticeable drag.

5) Mechanical decoupling: We provide users the flexibility to completely disconnect PedalCell from the rim when not needed, thus eliminating all mechanical drag.

Does PedalCell use a battery?

PedalCell does not use a battery. Batteries are great for storing power long-term but are not the best solution for extended outdoor use and real-time power generation. Our patented CadenceX technology uses supercapacitors over batteries due to their advantages of:

1) 10-20% Higher charge/discharge efficiency

2) 20X longer lifespan

3) Wider outdoor temperature ranges

4) Safety for volatile power

CadenceX technology can provide charge while stopped for up to 30 secs- 1 minute. Users who need to store power when stopped can use PedalCell to charge a battery pack.

What can I power with PedalCell?

PedalCell can power nearly any USB device through its two USB-C ports. Examples include bike lights, smartphones, GPS navigators, cameras, battery packs and more. A USB-C to A adapter is included in the box for backwards compatibility.

Can PedalCell power devices while stopped?

PedalCell can power USB devices for up to 30 seconds when stopped. It is worth noting that most USB devices have built-in rechargeable batteries, allowing them to stay powered for many hours when stopped. We recommend riders who need long-term charging when stopped/off their bike use PedalCell to charge a small external battery (~5000 mAh).

How does PedalCell work in the wet and mud?

Power dropouts from rim debris are rare and go unnoticed with PedalCell thanks to our mechanical and electrical design. Our Generator's spring and o-ring are spec'd to maintain grip in wet conditions as well as operate around debris. In the case of lost power, PedalCell's CadenceX technology operates as a backup to supplement charge until contact is made.

Is PedalCell noisy?

PedalCell is inaudible during use. Even once you consider the surrounding wind and drivetrain noise from a bicycle.

What is PedalCell's top speed?

PedalCell's top speed is 40mph (64 km/h). This limit is for O-ring longevity. At higher speeds, O-Ring stretching can occur which reduces its operating life. Riders are able to clearly see when this occurs. We recommend that riders decouple from the rim if high speeds are expected for continuous periods. We're considering releasing an o-ring with a higher top speed depending on rider feedback. Email info@pedalcell.com to inquire about testing this high-speed O-ring!

What is CadenceX Technology?

PedalCell's patented CadenceX Technology is the first of its kind in the bicycling space. CadenceX leverages supercapacitors to stabilize power output at varying ride speeds. Supercapacitors are energy storage, similar to batteries. However, supercapacitors are a much better fit to work with the unstable power output of a cyclist. Supercapacitors have multiple advantages over traditional lithium-ion batteries. These include:

Greater efficiency

Longer outdoor lifespan

Larger temperature operating ranges

Faster charge/discharge capabilities

CadenceX technology allows the supercapacitors to automatically supplement PedalCell's Generator power. CadenceX determines when to activate the supercapacitors based on a host of data from acceleration, device power needs, and speed. CadenceX communicates with algorithms onboard PedalCell's processor to ensure that devices are kept at their fastest charging rate via continuous USB negotiation. Your devices charge is kept constant even when:

Slowing down in a turn or up a hill

Charging during slow accelerates from a stop

Rare generator skips or slippage in the rim (ie. excessive rim mud buildup, ice, etc.)

Faster charge/discharge capabilities

CadenceX works alongside PedalCell's custom Generator and proprietary firmware to achieve industry-leading efficiency and power output. CadenceX's supercapacitor architecture is patented in the USA (patent no. 10727688) and is currently pending in AU, CA, and EU.

Is PedalCell's performance data public?

Which USB Charging Standards are supported?

PedalCell implements the following standards for its high power port:

USB-C CC 5V, 3A*

Dedicated Downstream Port: 500mA + 900mA

USB Battery Charging Specification BC1.2 + YD/T 1591-2009: up to 1.5A

1.2-V mode: up to 2A

2.7-V Apple device profile: up to 2.4A

A high-quality cable must be used to see expected performance. PedalCell's CadenceX technology constantly re-negotiates any time there is a speed change to ensure devices are kept in their highest charge state while maintaining a safe output.

*PedalCell consciously limits the USB-C CC profile 5V, 3A to a maximum of 2.4A. Device compatibility is not affected by this limit.
