Based on 18 reviews Write a review


The Fat-Tad Sun Tadpole trike is a beast on trails and can conquer almost any terrain. With the fat 4" wide tires, rear coil-over suspension, and integrated front suspension, the Fat-Tad climbs over obstacles with ease and keeps you stable.

The independent fork intergrated front suspension smoothes out the terrain
Independent Front Suspension

The electric Fat-Tad features an independent, fork-integrated front suspension on each front wheel in addition to rear coil-over suspension. Combined with the massive 4" tires, this trike can soak up the bumps!

The rear coil-over suspension helps cushion the rider from the trails
Rear Coil-Over Suspension

The rear coil-over suspension adds cushion right where it is needed, under the rider's seat. The suspension bushing and swingarm design allow the rear wheel to articulate independently from the front wheels for the smoothest ride possible.

A large easy-to-read LCD display with a backlit display makes it easier to read.
Easy-To-Read Segment Display
The Electric Fat-Tad features an easy-to-read backlit display with large text on an articulating mount. This advanced segment LCD includes a battery meter, speed, and trip distance readout, and programmable top speed limit.
The versatile 3 chainring will provide a large range of gears to conquer any type of terrain.
Versatile 3x8 Gearing
The Fat-Tad features a 24-speed drivetrain, providing you with a wide range of gears to help you tackle anything that might come your way; from hills to straightaways, you'll be prepared to keep on pedaling.
The rear geared hub motor provides 500 - 1000 watts and an impressive 84N-m torque.
500-1000 Watt Geared Hub Motor
The 500-1000w Electric Bike Technologies fat bike rear geared hub motor features impressive 84N-m torque and a USA handbuilt wheel with single-butted 12-13 gauge spokes for durability.
To get moving use the twist throttle to engage the motor
Thumb Throttle
The easy-to-use twist throttle allows you to engage the motor whenever you need it. Use the throttle to get a boost when starting from a stop or to help get up to cruising speed. The Fat-Tad also features a pedal-assist sensor (PAS) for operation.

How to Measure Your X-Seam

At Electric Bike Store, we like to use the X-Seam measurement to fit riders on recumbent trikes, and inseam to fit riders on upright trikes (like the Sun Traditional).

We use this measurement to adjust your trike to fit you out of the box, but it's simple to adjust your trike later to suit your preferences. This is just a rough measurement to make things easier for you.

image show that how you can measure you X-scale ,1/2 the length of the board

Alternatively, if you like reading and diagrams...

To measure your X-seam, you'll need a tape measure, a sturdy board (like a piece of plywood or an ironing board), and an assistant to help you. If you currently ride a recumbent bike, you can use that to take the measurement instead of the board.
