E-Bikes Certification:Evaluating and Testing to UL

Evaluate, test and certify to UL , the Standard for Electrical Systems for eBikes

Investigating potential hazards is a fundamental part of building consumer trust and protecting brand reputation. With that said, new strategies and protective circuitry will be required for safe operation as e-bike technology evolves.

To help assess the safety of e-bikes and electrically power-assisted cycles (EPACs), we involved industry leaders in developing next-generation e-bike safety requirements for UL , the Standard for Electrical Systems for eBikes. This Standard offers electrical and fire safety certification by examining e-bikes&#; electrical drive train system, battery system and charger system combinations.

UL covers:

  • e-Bikes (typically sit-to-operate and over-the-road use) and pedal-assisted electric (pedelec) cycles
  • The risk of electric shock during charging over the life of the product, as well as other potential electrocution hazards

The Standard does not evaluate for the operator&#;s ability to maintain control while riding.

UL Solutions is recognized by Occupational Safety and Health Administration (OSHA) as a Nationally Recognized Testing Laboratory (NRTL) to certify micromobility products to UL , the Standard for Electrical Systems for eBikes.

U.S. Consumer Product Safety Commission (CPSC) Micromobility Safety Guidance

On December 20, , the U.S. Consumer Product Safety Commission&#;s (CPSC) has called on manufacturers, retailers, importers, and distributors of micromobility devices to comply with established UL safety standards. This includes products covered by UL and UL , which address electrical systems in personal e-mobility devices (such as hoverboards) and eBikes, respectively.

New York City Council&#;s law on micromobility devices and batteries

In a move to strengthen fire safety of e-bikes, e-scooters, and the lithium-ion batteries that power such devices, on March 2, , the New York City Council passed Initiative 663-A, mandating e-bikes, e-scooters, e-mobility devices, and light electric vehicle (EV) battery packs to be third-party certified. On March 20, , New York City Mayor Eric Adams signed this into law. With this new law, any company selling, leasing or distributing micromobility devices, such as e-bikes or e-scooters, has until September 16, , to obtain certification from UL Solutions or another National Recognized Testing Laboratory (NRTL) to:

What Questions Should I Ask Before Buying an Electric Bike?

In today&#;s installment of the 3 Minute Electric Bike Video Series where we are demystifying electric bikes we are talking about things you might want to ask a vendor before an electric bike purchase.

Ask about the battery.

Ask the vendor who the manufacturer is. You want to hear names like Panasonic, Samsung all the big names. If you don&#;t hear a name you recognize, just ask a little bit more, they actually might be related to a larger company. You also want to ask about the capacity of the battery. A very common rating is 36 volts and 10Aph. On this type of battery rating, you can get 20 to 40 miles per charge, depending on your riding style and how much you pedal. That&#;s a very good base line to start with.

Ask about the motor.

Ask the vendor about the wattage in the motor bolt, the continuous wattage rating and peak wattage rating. The number you typically see on your screen when you are doing internet research is the continuous wattage rating. For example; you might see 500W, that means that&#;s the wattage that the motor is able to put out on a continuous level for the duration of the charge. The peak wattage rating is what the motor is capable of on heavy load situations. Climbing a hill for example naturally draws more current from the battery. It is good to know both numbers, not just the continuous wattage number.

Ask about the bike components.

It came to my mind that electric bikes are bikes first and the electric part is secondary, so ask about the bike itself. You want to about what kind of componentry is involved especially the shifting system and the braking systems, You want to hear names like Shram or Shimano, but also inquire about the motor of the particular component that&#;s in place. Shimano has a broad spectrum of the rails that they put out, for example. Some are on bikes that cost $150, but sometimes, they have bikes derails by themselves that cost $150, so there is quite the spectrum there. Make sure you know specifically what you are getting into, don&#;t settle with just the manufacturer&#;s name.

Ask about their customer service.

There is an invincible part of the bike that&#;s really keen, it&#;s the customer service component. Ask about the warranty. Warranties that are 12, 18 or 24 months are pretty common. You also want to know what the response time is like with the customer service department. In a pre-sale situation, ask them a question by or , and see how long that takes to get back to you. If you hear from them in 24hrs, that&#;s pretty good, if it takes a week for them to respond, you should see some red flags. If they are this way before the sale, what will it be like after the sale? If you need help, the customer service department is going to be your first point of contact.

There are a number of things you want to ask about, ask about the battery, ask about the motor, and ask about the components on the bike and do a little research on their customer service.
