Suspension

Four-Point Shock Absorption

Front and rear suspension work together to soak up potholes, curbs, roots, and gravel, so the ride stays smooth on city streets, mountain trails, sand, or snow. Wherever the road takes you, the suspension filters out the vibration before it reaches you.

Power

Up to 750W Motor, 1500W Peak

80 Nm of torque and a 30-degree climb rating mean real climbing power without breaking a sweat, on both setups. Five assist levels let you dial in exactly how much help you want, from a light boost to a full electric ride. Two motor and battery setups available, see the comparison below to pick the right one for you.

Range

Go Further on One Charge

A 48V removable battery, available in 748Wh or 960Wh depending on your setup, delivers up to 25 to 70 miles per charge depending on terrain, assist level, and which battery you choose. Charge it indoors or out.

Ride Seen, Day or Night

Why Calder

Most fat-tire e-bikes at this price cut corners somewhere. Here is where Calder does not.

Real Suspension, Not a Sticker

Dual front and rear suspension is a functioning system, not a marketing line on a bike that rides like a plank.

Power That Does Not Fade

Hills and headwinds do not slow you down the way they do on the underpowered hub motors most competitors use.

Range for Real Adventures

Genuinely large battery capacity for this category, built for full days on the trail and just as capable of covering your daily commute.

Backed, Not Abandoned

A real warranty and a real support team behind it, so you are not on your own the moment something needs attention.

Three Ways to Ride

Pedal Assist

Pedal as usual and let the motor add power behind every stroke. Ideal for extending range and getting light exercise in.

Throttle

Twist and go, no pedaling required. Best for quick starts from a stop or when you just want to cruise.

Manual

Switch the motor off entirely and ride it like a standard bike whenever you want the workout.

Common Questions

The 20 in / 960Wh setup is built for maximum range and top speed, best if you want the longest rides and the most off-road performance. The 16 in / 748Wh setup is lighter and more agile, with a top speed closer to most e-bike speed limits, a good fit for lighter riders or anyone who wants to stay well within local regulations. Both share the same motor peak power, suspension, and frame.

Calder is rated for up to 40 to 70 miles per charge on the 20 in / 960Wh setup, or 25 to 68 miles on the 16 in / 748Wh setup, depending on rider weight, terrain, and assist level. Both batteries are removable and can be charged indoors or out.

Calder arrives 90 percent pre-assembled. A few basic steps are required to finish setup, and full instructions are included in the box.

Calder is covered by a 1 year warranty on the motor, battery, and charger.

You have 30 days from delivery to return Calder for a full refund. Return shipping is the customer's responsibility.

Top speed depends on which setup you choose: up to 25 mph on the 16 in / 748Wh setup, or up to 31 mph on the 20 in / 960Wh setup. E-bike speed and classification laws vary by country, state, and province, and the 25 mph setup is a closer match to most e-bike regulations outside the United States. We recommend checking your local e-bike regulations before choosing your setup or riding at higher assist levels, particularly outside the United States.

Orders ship within 6 to 8 business days for US, UK, AU, and CA. You will receive a tracking number by email as soon as your Calder ships.
