Longbikes Eliminator Recumbent Bike


Longbikes Eliminator Recumbent Bicycle

In 2005 Longbikes introduced their Short Wheel Base (SWB) – Under Seat Steering (USS) Single Eliminators! Always a standout among high-quality rugged short-wheel-base (SWB) under-seat-steering (USS) recumbents the stout frame on the Eliminator gains an adjustable pedal boom and new chain idler with easily replaceable sprockets. It makes it stiff, stable and warranted for riders up to 300 lb.

The new adjustable pedal boom works with the adjustable seat allowing optimal weight distribution loaded or unloaded. Move the seat and pedals a bit to the rear when not carrying large loads; forward for touring with a load. Moving the pedal boom to center your weight requires changing the length of the front chain so you won’t do it often.

Features and Options:

Chain management:

The 3 chains on this bike keep chain noise to a minimum. The front chain tension is adjusted by moving the pedal boom slightly. The center chain is adjusted with an eccentric. The rear chain which does all the shifting is similar in length to a traditional bike to keep chain weight near what Shimano designed for helping the rear derailleur work like it should to give you crisp shifting. On the other hand, the Slipstream shifts well too.

The crankset has a single 32 tooth chain ring. Behind that, near the headset, there is a pair of adjustable idler sprockets to raise the chain above the fork and create shorter manageable lengths of chain, rather than one really long chain. Under the seat, there is a spider that carries four chainrings. The spider is driven by a chain from the inner of the pair of chainrings. All the “front” derailleur is here under the seat. It shifts well but like on our RANS Screamer tandem I sometimes miss being able to see it shift. It is complicated, but it works well.

Custom Components:

Longbikes has their our own custom recumbent crankset made, chain rings too. The chain idlers, frame, and seat hardware are made in Colorado by Longbikes. They are beautifully designed and finished, as Longbikes is famous for.


Longbikes standard “Hip Hinge” seat provides for independent adjustment of seat tilt and back recline. Seat bottom rotates on the seat mount for tilt adjustment. This allows you to set a posterior tilt to prevent you from sliding out without causing so much back recline that you strain your neck. The four incremental adjustment positions allow a seat to back angle of 95-115 degrees in 5-degree increments to fine tune the back position as well. A pair of adjustable struts provides support between the frame and the seat assembly.


Longbikes doesn’t like wimpy components. Their dovetail seat rail and mating mount are examples of their attitude toward design. Not light duty parts, they won’t slip. More work on their part, but Longbikes design philosophy usually doesn’t do things the easy way!
