Eunorau META275 48V/13Ah 500W Electric Bike

Frequently Asked Questions

How does the torque sensor work?

The torque sensor measures the force you apply to the pedals in real-time. When you pedal harder, it delivers more motor assistance. When you ease up, the motor reduces power. This creates a natural, bike-like feel that's more intuitive and efficient than basic cadence sensors that only detect whether you're pedaling or not.

What's the real-world range on a single charge?

Range varies based on rider weight, terrain, assist level, and riding style. Most riders get 35-45 miles on the standard 13Ah battery. With the optional second battery (15Ah or 17Ah), you can achieve 50-65+ miles. Using lower assist levels and pedaling more extends range significantly.

Can I ride it in the rain?

Yes, the META275 is water-resistant with waterproof connectors on the display and electrical components. You can ride in light to moderate rain without issues. Avoid deep puddles, pressure washing, or submersion. Always dry the bike after wet rides and store it in a dry location.

Is it street legal?

Yes, the META275 meets Class 2 e-bike specifications in most U.S. states (throttle + pedal assist, max 20 mph). It's legal on most bike paths, roads, and trails where bicycles are permitted. Always check your local and state regulations, as laws vary by location.

How much assembly is required?

The bike arrives 85% assembled. You'll need to attach the front wheel, handlebars, pedals, and adjust the saddle height. All necessary tools are included. Most people complete assembly in 30-45 minutes. Assembly videos are available online for guidance.

Can I add a second battery?

Yes, Eunorau offers optional second batteries in 15Ah and 17Ah capacities. The second battery significantly extends your range, making the META275 perfect for longer commutes or all-day adventures. Contact us for second battery options and pricing.

What's the difference between step-through and step-over frames?

The step-through frame has a low top tube, making it easy to mount and dismount—ideal for riders who wear skirts/dresses, have mobility concerns, or prefer easier access. The step-over frame has a traditional diamond design that offers slightly more rigidity and a sportier feel. Both frames offer identical performance.

How fast can it go?

The META275 reaches 20 mph with pedal assist and throttle, which is the legal limit for Class 2 e-bikes in most states. Some riders report slightly higher speeds (25-32 mph) when pedaling hard downhill, but the motor assistance cuts off at 20 mph.

What maintenance does it need?

The META275 requires minimal maintenance: keep tires properly inflated, charge the battery regularly (even during storage), keep the chain clean and lubricated, and check brake pads periodically. Hydraulic brakes require less maintenance than mechanical brakes. Annual tune-ups are recommended for optimal performance.

What's covered under warranty?

The META275 comes with a 2-year limited warranty covering manufacturing defects in the frame, motor, battery, and electrical components. Normal wear items (tires, brake pads, chain) are not covered. Warranty service is provided through Eunorau. Keep your purchase receipt and register your bike for warranty coverage.

Frequently Asked Questions

How does the torque sensor work?

The torque sensor measures the force you apply to the pedals in real-time. When you pedal harder, it delivers more motor assistance. When you ease up, the motor reduces power. This creates a natural, bike-like feel that's more intuitive and efficient than basic cadence sensors that only detect whether you're pedaling or not.

What's the real-world range on a single charge?

Range varies based on rider weight, terrain, assist level, and riding style. Most riders get 35-45 miles on the standard 13Ah battery. With the optional second battery (15Ah or 17Ah), you can achieve 50-65+ miles. Using lower assist levels and pedaling more extends range significantly.

Can I ride it in the rain?

Yes, the META275 is water-resistant with waterproof connectors on the display and electrical components. You can ride in light to moderate rain without issues. Avoid deep puddles, pressure washing, or submersion. Always dry the bike after wet rides and store it in a dry location.

Is it street legal?

Yes, the META275 meets Class 2 e-bike specifications in most U.S. states (throttle + pedal assist, max 20 mph). It's legal on most bike paths, roads, and trails where bicycles are permitted. Always check your local and state regulations, as laws vary by location.

How much assembly is required?

The bike arrives 85% assembled. You'll need to attach the front wheel, handlebars, pedals, and adjust the saddle height. All necessary tools are included. Most people complete assembly in 30-45 minutes. Assembly videos are available online for guidance.

Can I add a second battery?

Yes, Eunorau offers optional second batteries in 15Ah and 17Ah capacities. The second battery significantly extends your range, making the META275 perfect for longer commutes or all-day adventures. Contact us for second battery options and pricing.

What's the difference between step-through and step-over frames?

The step-through frame has a low top tube, making it easy to mount and dismount—ideal for riders who wear skirts/dresses, have mobility concerns, or prefer easier access. The step-over frame has a traditional diamond design that offers slightly more rigidity and a sportier feel. Both frames offer identical performance.

How fast can it go?

The META275 reaches 20 mph with pedal assist and throttle, which is the legal limit for Class 2 e-bikes in most states. Some riders report slightly higher speeds (25-32 mph) when pedaling hard downhill, but the motor assistance cuts off at 20 mph.

What maintenance does it need?

The META275 requires minimal maintenance: keep tires properly inflated, charge the battery regularly (even during storage), keep the chain clean and lubricated, and check brake pads periodically. Hydraulic brakes require less maintenance than mechanical brakes. Annual tune-ups are recommended for optimal performance.

What's covered under warranty?

The META275 comes with a 2-year limited warranty covering manufacturing defects in the frame, motor, battery, and electrical components. Normal wear items (tires, brake pads, chain) are not covered. Warranty service is provided through Eunorau. Keep your purchase receipt and register your bike for warranty coverage.
