Short answer
Check the rack tube before buying panniers: ORTLIEB offers 20 mm hooks for 17-20 mm tubes, which it says are often used on e-bikes. For the e-bike's own battery, CPSC advises using the supplied charger, not a charger marketed as universal. 16 CFR 1512 and UL 2849 cover the bike and its electrical system, not add-on accessories. Check your valve with the valve finder.
Key facts
- Tire and rim pressure limits
- Schwalbe says the sidewall pressure range should never be exceeded or undershot, and that heavier loads need higher pressure.[1]
- How to check your valve
- Look at the stem. A thin stem (nominally 6 mm, per Park Tool) with a small locknut at the top is Presta. A wider stem, about 8 mm (5/16 in), is Schrader. Dunlop/Woods has a narrow tip over a large ring. The valve finder on this site walks through each.[2]
- Pumps and inflation
- Not confirmedNothing we read is specific to e-bikes; use a pump whose maker names your valve.
- Tubeless and repair
- Not confirmed
- Handlebar and mounts
- Not confirmedMeasure your bar; no source says which diameter e-bikes use.
- Bags and racks
- ORTLIEB offers optional 20 mm QL2.1 hooks for racks with 17-20 mm tubes, which it says are often used on e-bikes. Brompton says Brompton Electric uses a dedicated Front Carrier Block, so it needs an Electric-compatible Front Bag with space for the battery.[3][4]
- Lighting rules
- 16 CFR 1512 sets requirements for bicycles, and CPSC says its definition includes low-speed e-bikes under 750 W and 20 mph; section 1512.16 requires reflectors. Riding rules for lights are set by place: California requires a white front lamp visible from 300 feet in darkness, Oregon one visible from at least 500 feet.[5][6][7][8][9]16 CFR 1512 is a product rule for bicycles sold in the US, not a riding law.
- Charging and batteries
- For e-bikes and other micromobility products, CPSC advises being present while charging, never charging while asleep, using only the supplied charger and unplugging once charging is done. It urges owners not to use chargers marketed as universal unless tested and approved for their device. UL 2849 is UL's standard for e-bike electrical systems.[10][11][12]CPSC's advice is about the e-bike's own battery, not USB bike lights. We recommend no chargers or traction batteries.
- Maker cautions
- CPSC says an incompatible charger can ignite a micromobility battery, and advises using the charger supplied with the device or a manufacturer-approved replacement.[11]
Watch out for
- ORTLIEB's standard QL2.1 inserts stop at 12 mm; 17-20 mm rack tubes need its optional 20 mm hooks.
- Brompton Electric needs its own Front Carrier Block and an Electric-compatible bag.
- UL 2849 and 16 CFR 1512 are bike-level standards; they do not certify a light, pump or bag you add.
- CPSC's charging advice is written for e-bike and other micromobility batteries, not for USB bike lights.

Questions
Will my panniers fit an e-bike rack?
Measure the rack tube. ORTLIEB offers optional 20 mm QL2.1 hooks for 17-20 mm tubes, which it says are often used on e-bikes; its standard inserts cover 8, 10 and 12 mm.[3]
Can I charge my e-bike battery with a universal charger?
CPSC urges e-bike owners not to use chargers marketed as universal unless tested and approved for their specific device, and to use the supplied charger or a manufacturer-approved replacement.[11]
Does UL 2849 cover my bike light?
No. UL describes UL 2849 as its standard for e-bike electrical systems; it is a vehicle-system standard, not one for standalone accessories such as USB lights or pumps.[12]
