How it works


The Original Bicycle Tandem Bar®, BUDDY BAR was originally designed for getting the efficiencies of riding a tandem, but doing it at a fraction of the cost. When we were testing BUDDY BAR, we found many more uses for buddybar, anything from training of newer riders and seasoned as well.

Friends, family and couples – young and old – now have no excuse of not being able to keep up when riding – you’re connected!

For cyclists and coaches, some of the training can include: pacelining, cadence training, heartrate training, drafting, and others.

Personal Trainers can add it to their “tool box” for a unique idea for cardio and get their clients outdoors.

Physical Therapists or other healthcare specialists with a goal of getting their patients/clients on a bicycle can add BUDDY BAR to their programs.

Go BUDDY BAR!  Ride…together!

Set Up:

The BUDDY BAR kit comes fully assembled in the mail.

  • The front bicycle attaching assembly connects to the frame rails of the back of the saddle. This will be the “captain” bicycle.
  • The rear bicycle attaching assembly connects to the stem of the bicycle. The stem must be a 1″ or 1 1/8″ stem. Quill or threadless should not matter.
  • BUDDY BAR has a quick coupler on both ends and connects both bicycles together, front to back (tandem style), which gives the immediate advantage of built in draft. That advantage is a one person aerodynamic profile, and two rider’s power.

Tools you may need to get started:

  • Allen wrench (4mm, 5mm, and/or 6mm)
  • “Regular” 7/16” wrench
For quill stem, you will need a large adjustable or crescent wrench
You may have to refer to the bicycle manufacturer’s handbook for any additional tools needed.

Front Bicycle Instructions (Captain)

Instructions are as follows:
  1. Take the angled T-bar and the step plate and position so the angled T-bar comes straight out of the back of the saddle(bending may be necessary to make it straight as some saddles have a little more bend in their frame rails).
  2. Take the bolts provided and cinch down to frame rails of saddle.
  3. Take male end of attaching hardware and attach to angled T-bar. Can be configured up or down, but we have found if it is down, there is more room for movement of buddybar.


Rear Bicycle Instructions (Stoker)

Mounting instructions are as follows:
  1. There are two types of stems that are used on most bicycles today:
  2. Quill stem:
    The quill stem has been around much longer, and it usually has a bolt that goes through the top of the stem down into the front fork.

    1.  Remove stem and handlebar by using a 5mm or 6mm allen wrench and loosening the bolt that is on the top of the stem.
    2.  Pull stem and handlebar assembly from headset.
    3. Take a large crescent wrench and unscrew nut on top of the headset.
    4. Remove headset nut and spacer from headset.
    5. Install BUDDY BAR connecting rod assembly either right side up or upside down(whichever has the most clearance).
    6. Screw on and tighten headset nut.
    7.  A tight turning radius might cause the stoker BUDDY BAR connecting piece to move around and not stay in place; this is by design, but will not affect performance of the ride. If you wish, get to a stopping place and readjust.
  3. Threadless headset:
    The threadless headset is the newer of the two, and it has a “top cap” with a bolt going through the top and screwing into a “plug” that is in the front fork. It also has a stem that mounts to the fork with one or two attaching bolts, and some spacers.

    1. Remove top cap.
    2. Loosen stem bolts
    3. Pull stem and handlebar assembly from fork.
    4. Install BUDDY BAR connecting rod assembly with head down or head up(usually head down gives more clearance). You may need to remove a small spacer to allow room for the connecting rod assembly.
    5. Replace stem and handlebar assembly onto fork(do not tighten stem nuts yet).
    6. Replace top cap. Screw down until there is no play in the headset(holding front brake helps to determine play).
    7. Straighten stem and handlebars and tighten stem bolts(usually to 4Nm).

Time to BUDDY BAR!

Riding Basics – Getting started:
Once BUDDY BAR is connected to both bikes, to begin riding, start off on a flat surface and rid out slowly together. You can independently brake as needed, or decide to use the brakes at the same time, to slow or stop.  Make sure the other rider is ready to start, slow down, go faster, or stop.

The system can stay in place!
Once the BUDDY BAR system is in place, you can leave in the connecting pieces and simply remove the bar when you’re done, and store in a place where it will not get easily damaged. All you need to do for your next ride is simply slide back the springs on both ends, clip in the bar, and you are ready to go!

Uninstalling the system
For the Front Bicycle/seat attaching kit:

  1. Loosen the bolts of the step plate connecting the angled T-bar to frame rails of saddle, and remove the seat attaching kit.
  2. Put the bolts back on the step plate to angled T-bar to keep the seat attaching kit pieces together
  3. Make sure you put the kit pieces that create the BUDDY BAR system (bar, seat attaching kit, stem attaching kit) all together in the same place so it will be easy to assemble in the future.
RIDE RESPONSIBLY and at your own risk! Follow the same cycling rules as you would riding independently (solo or with other riders) or on a Tandem Bicycle.  Communication is key!


warning icon WARNING

Read all safety and user guidelines before using BUDDY BAR.  BUDDY BAR is safe if used properly.  If not used properly, you can risk injury and even death.  So let’s keep it on the safe side, please! Print off and keep this Safety and User Guide in a safe place for future reference. 

The BUDDY BAR is made of 100% steel and proudly manufactured in the USA.

  • Fits most bicycles, although not recommended for bicycles with carbon handlebar stem set.
  • Follow all setup instructions carefully to ensure proper fitting of BUDDY BAR to both bicycles.  If unsure of set up, contact your local bicycle shop for installation.

warning iconYou and your riding partner are using buddybar at your own risk.  

warning iconAdult supervision required for riders under 18.

warning iconConnect two bicycles only; do not connect more than two bicycles with more than one BUDDY BAR.

The steel angled T-bar, the connector piece on the saddle of the Captain’s bicycle (the bicycle in front), might stick out farther than the seat.  You may leave this piece in place for consecutive rides, or choose to remove it. If you decide to leave it on the bicycle, be aware that some of it sticks out from the seat and you can risk falling on it or hitting it thus causing injury.

warning iconAt every use, check connectors on both ends, tighten screws, and ensure the connector ball is securely fastened in end pieces.  If any spacing is apparent or connector ball is not secured, do not use BUDDY BAR and contact us immediately.

warning iconDo not use is connector pieces are broken or not working, or if bar is bent. Please contact us immediately.

warning iconNot for first time or just learning riders.  Riders must be able to ride on their own before attempting to be connected to BUDDY BAR and another bicycle and rider. Only ride within the cycling abilities of both riders.

  • Both riders must be alert, especially if riding on a road with cars.  As riding any bicycle, cyclists are obliged to obey the rules of the road.  Each rider is using BUDDY BAR at your own risk.    
  • Each rider must have control over their own bicycle – communication is KEY in riding with buddybar, as each rider has their own set of brakes and can steer (limited steering on the back bicycle, but still ability to steer within a degree of movement).
  • It doesn’t matter which position the riders are in – who rides in front or back.  You have to thoughtfully plan your ride, depending on environment (road or trail), weather, and experience of each rider.
  • For training purposes, sometimes the experienced rider is recommended to ride in the back position (the Stoker position) with less experienced rider in the front position (the Captain position) so they can better observe the rider up front, and can also instruct the movements of that rider.  
  • Braking:  practice braking often – determine who the stronger rider is and discuss potential safety and prepare for emergencies.   This is a common practice for all riders, whether riding independently without buddybar in a group, or even if on a regular tandem bicycle.
  • The BUDDY BAR allows for a big turning radius, unlike a tandem bicycle.  However, it is not recommended to allow the bar to be at 90 degree angle (where connected bikes are parallel or side by side to each other) for a long period of time.

warning iconIf one cycle falls, either front (“Captain” position) or back (“Stoker” position), there is a risk both bicycles could fall.  You have to evaluate every situation you encounter to determine if you are able to prevent falling or lessening a fall.  We encourage each rider to ride responsibly and at the level they are able to control the bicycle safely.

warning iconBUDDY BAR is not intended or recommended to be used as a device for anything other than connecting two bicycles together.

warning iconFollow safety guidelines of the bicycle manufacturers of the bicycle you will be connecting and riding.

warning iconWearing a helmet is suggested, or as guideline for wearing helmets as it applies in your state.  It may be required by law for riders under 18.

warning iconAbide by all road rules and ride responsibly.
