Delivery options
How delivery works
Your item’s shipping method and price are confirmed in the shipping calculator and at checkout. Here is what each delivery path means.
Driveway freight delivery
Your equipment is palletized and protected. The freight carrier schedules delivery, then uses a liftgate to lower it to your curb or driveway. Moving it inside and unpacking it are up to you.
Inside delivery & assembly
When selected and available for your address, the delivery team brings the equipment into the room, assembles and tests it, then removes the packaging.
Full truckload
For commercial builds and multi-pallet orders, a dedicated trailer keeps the full order together in one delivery. We confirm the unloading plan before the truck ships.
Size: 70" × 23" × 50" tall
Doorways: 23" at its narrowest, so it clears a standard 32" door
What Remanufactured Means
Every remanufactured machine is fully disassembled, deep cleaned, repaired or re-parted to factory spec, then tested under load before it ships. Backed by one year parts and labor, with extended coverage available.
Warranty Coverage
New and remanufactured equipment are both covered for one year, parts and labor, backed by us. Extended protection is available on either through BAG Care+. Used equipment is sold as-is with no warranty coverage, and is described honestly before you buy. We service nationwide - every ZIP code in the country - so coverage travels with the machine.
30-Day Returns & Exchanges
Change your mind within 30 days of delivery and you can return the machine or exchange it for a different size, color or configuration.
Return shipping is the customer's responsibility and a 15% restocking fee applies to preference returns and exchanges. Freight items must go back packaged to the same standard they arrived in. We will tell you exactly what that means before anything is collected.
Anything that arrives damaged or fails under warranty is handled separately and carries no restocking fee. Full terms are in our Returns, Exchange & Refund Policy.

CTX/ Build-a-Gym absolutely CRUSHED IT! I had been struggling with numerous manufacturers trying to get a seated leg press/extension that’d ship to Alaska. When I found CTX, they went above and beyond to get my Fractal packaged and shipped with no hassle. I HIGHLY recommend these folks to anyone looking for solid commercial quality equipment for their home.

CTX stands by their products. I recently purchased a Precor elliptical from them & it arrived with a mechanical flaw. They coordinated with a technician to get my product fixed like new. They accomplished this despite the fact that my home was two states away. Special thank you to Nichole for staying accessible and attentive throughout the process!

They came prepared and were very fast and efficient. They offered to help us move around other equipment to ensure we loved our gym! Super nice people and an amazing company! I would highly recommend working with them. Oh and the equipment itself is high quality and looks great in our home gym!

Rebuilt in our Jarrell, TX shop
What remanufactured means here
Every machine we sell as remanufactured goes through the same process, whatever the brand or the price. Not a wipe-down and a price tag.
-
Inspected and stripped down
Assessed frame to console, then taken apart and checked part by part. Nothing gets judged from the outside.
-
Moving parts rebuilt or replaced
Every moving and touched component, from belts and cables to bearings, bushings and grips, is evaluated and rebuilt or replaced, then the machine gets a full cosmetic restoration.
-
Refinished and rebuilt to spec
Electronics bench-tested, frames and welds checked, panels refinished, then reassembled to the manufacturer's specification.
-
Tested under load
A full operational cycle under load before it ships. Anything that fails the final check goes back through service, not onto a truck.
Get an email when new machines land
Good units go fast. We'll email you when new machines land - nothing else.

Commercial-grade equipment, inspected and supported by warranty.
The Precor RBK 835 Recumbent Bike delivers 15° seat rail with crank offset for KOPS biomechanics, Air Flex floating seat back, one-handed seat adjustment on or off the bike, dual-sided pedals, deep-groove sealed precision bearings, 14" step-through width with 4" step-over height, touch HR handlebars, and P30 console - 210 lb commercial frame, 70"×23" footprint. The biomechanics specification on the RBK 835 is more precisely engineered than a standard recumbent bike: the seat rail is set at 15° with a specific offset from the crank axle that places the knee directly over the ball of the foot (or pedal spindle) when the pedals are at the 2 and 8 o'clock positions. This is the same KOPS principle applied on the UBK 865 and RBK 865, but defined here with the specific clock-position reference - the 2 and 8 o'clock positions are where the knee joint is at its most mechanically loaded moment through the pedaling arc, and having the knee directly over the pedal spindle at those positions minimizes anterior knee shear force at the highest-load instant of the stroke. The Air Flex seat back uses a floating suspension system that allows the seat back to move with the user's lumbar and sacral motion rather than being a fixed rigid surface - not just lumbar-shaped padding, but a backrest that tracks the user's movement. This is meaningfully different from a fixed lumbar support: a fixed pad supports one lumbar position; a floating suspension accommodates the small postural adjustments users make throughout a session without resistance from the seat back. The 4" step-over height is among the lowest in commercial recumbent bikes, specifically benefiting users with balance limitations, joint stiffness, or post-surgical mobility restrictions.
Dual-sided pedals with integrated straps accommodate feet of all sizes with or without the strap. Deep-groove sealed precision bearings for smooth operation and long service life. P30 console displays resistance, RPM, speed, watts, HR, calories, and time metrics. 210 lb Precor RBK 835 commercial frame, 70"×23" footprint. Remanufactured.

Key features
15° Seat Rail · Crank Offset · KOPS at 2 & 8 O'Clock
Seat rail set at 15° with crank offset positions the knee directly over the pedal spindle at the 2 and 8 o'clock positions - the moments of highest mechanical load through the pedaling arc. KOPS alignment at peak-load positions minimizes anterior knee shear force where it matters most, rather than only at the bottom of the stroke where load is lower. Consistent with Precor's upright bike biomechanics applied to the recumbent position.
Air Flex Floating Seat Back · 4" Step-Over · One-Handed Seat Adj.
Air Flex floating suspension allows the seat back to move with the user's lumbar motion rather than holding one fixed position - accommodating the small postural adjustments that occur throughout a session without resistance from the seat back. 4" step-over height among the lowest in commercial recumbent bikes, specifically for users with balance limitations or post-surgical mobility restrictions. One-handed seat adjustment from the saddle without dismounting.
Dual-Sided Pedals · Sealed Precision Bearings · P30 Console
Dual-sided pedals with integrated straps usable on either side - entry without orientation requirement, strap or no-strap flexibility. Deep-groove sealed precision ball bearings on the bottom bracket for smooth operation and long service life without maintenance access. P30 console displays resistance, RPM, speed, watts, HR, calories, time elapsed, time remaining, and segment metrics.
