Sun SKR Eco Delta Review

Sun Eco Delta

The Sun Seeker Eco Delta trike is a great choice for riders seeking comfort, accessibility, and affordability. Its upright, padded mesh seat is highly adjustable, making long rides much more enjoyable, while the higher seating position and delta configuration (with two rear wheels) make it significantly easier to get on and off compared to lower-slung tadpole trikes—perfect for those with mobility issues or new to triking. It’s also one of the most budget-friendly recumbent trikes on the market, offering solid value without sacrificing key features. Overall, it’s a smooth, relaxed ride that’s easy to handle and easy on the wallet.

Seat: The Eco Delta features a breathable mesh seat with a foam-padded bottom, ensuring comfort during long rides. The seat is adjustable both in angle (from 40° to 90°) and position along the frame, accommodating various rider preferences and sizes. This adjustability allows for a more upright or reclined riding position, enhancing comfort and reducing neck strain.

Drivetrain: The trike uses a reliable 7-speed Shimano Tourney rear derailleur paired with a simple single front chainring, making it easy to operate and maintain. The twist shifter on the handlebar allows for smooth and intuitive gear changes, ideal for casual riders who want straightforward control without complex gearing. It’s well-suited for flat to moderately hilly terrain.

Wheels: All three wheels are 20 inches in diameter, offering a good balance of stability and maneuverability. The alloy rims are lightweight yet durable, and the wide tires help absorb road vibrations for a smoother ride. The rear wheels provide a solid, planted feel on the road and contribute to the trike’s stable cruising experience.

Accessible: Unlike tadpole-style trikes with two front wheels, the Eco Delta’s delta configuration (one front wheel and two rear wheels) places the seat higher, making it easier to get on and off. This design is particularly beneficial for riders with limited mobility or those new to tricycles

Ride: The ride feel of the Sun Seeker Eco Delta is smooth and relaxed, ideal for casual cruising and flat terrain, though it’s best taken easy on turns due to a slightly higher center of gravity.

Pros:

  • A very comfortable seat bottom
  • Easier to get on and off of compared to a tadpole style trike
  • Low price

Cons:

  • A little more tippy than a Tadpole style trike
