The latest design from a railrider with over 60 years of railbiking experience.

The BENTLEY RAILBIKE on a cool day.

CONSTRUCTION PLANS include 6 pages of text with detailed construction sequence and parts list keyed to the drawings, plus 10 sheets of drawings with most parts rendered full scale.

+ Easy construction - no welding or complex machining.
+ Adjustable outrigger wheel height.
+ Detach outrigger with 3 pins - folds after removal.
+ Wheel guide lift lever.

This is a proprietary design, and a patent shall be applied for in the near future.

A LICENSE (plans included) to construct a railbike in accordance with these plans may be purchased for $25 (US DOLLARS).

Make that $27 if you write a check on any bank, even a US bank, that is physically located outside the US.

If you wish to purchase Railbike PLANS:


SEND me an EMAIL ( bentley@northnet.org ) that includes your NAME, HOME ADDRESS, and TELEPHONE NUMBER so I can get in touch with you by other means in the event there is any mixup in our future communications. Write 'RAILBIKE' on the subject line of your email.

Once again, ALL orders must include your full NAME, ADDRESS, and PHONE NUMBER.
(I will have your EMAIL address when you Email me.)

ALL Railbike PLANS are sent by Email as attachments. I include printing instructions so they will print at the correct size.

If for any reason you send me a Railbike PLANS order by mail, Be VERY sure your EMAIL ADDRESS is CLEARLY spelled out. It is often impossible to distinguish the letter 'O' from zero and ells from the number one. And be doubly sure to include your PHONE NUMBER.

The easist way to pay is to use PayPal. Send payment to bentley@northnet.org and do me a kindness by clicking 'send money to a friend'.

In the United States I accept personal checks and money orders made payable to Richard Bentley. I will even accept cash, but NO CREDIT CARDS.

Outside the US I accept International money orders made payable to Richard Bentley (in US dollars) or cash. If you send foreign currency make sure that it is sufficient to cover exchange rate PLUS a reasonable fee that my bank will charge me for the transaction. Cash is usually safe in the USA but I am not responsible if it gets 'lost'.


Your PayPal account should be linked to your bank account and MUST be in US DOLLARS.

If you INSIST on making a PAYPAL payment charged to a CREDIT or DEBIT card you must add on $2 (send $27) because PAYPAL charges $2 more for processing such payments.

AND... please follow these INSTRUCTIONS:

You are NOT making a PURCHASE of GOODS or SERVICES, you are paying for INTELLECTUAL PROPERTY. SO, when you click on 'Send Money' in PayPal, after entering my Email address from above (carefully 'copy and paste') AND have entered the amount of the payment, please click the button labeled 'Sending money to family or friends'.

IF you would rather click the button labeled 'Paying for goods or services' then I request that you add an extra $2 (in addition to anything else you may have had to add) for the fee PayPal shall charge me.

And do NOT forget to include

LATEST Railbike Construction NOTES


A railbike, sometimes called a 'rail bike', is a standard bicycle with attachments that allow the bicycle to be ridden easily along on a railroad track. Most abandoned railroads are in pretty poor shape. Any good railbike design must be able to cope with broad flattened rails, narrow worn rails, and weeds so thick you can't see the rails.

ALWAYS KEEP IN MIND, you should use railbikes ONLY on ABANDONED lines!!

The attachments to the bicycle consist of a FRONT WHEEL GUIDE, and an OUTRIGGER to the opposite rail.

The FRONT WHEEL GUIDE attaches to the front wheel axle, and steers the bike to keep it on the rail. The GUIDE may be raised off the rail with a small lever mounted on the handlebar. This makes it possible to ride (SLOWLY!) past road crossings and other minor obstructions without getting off the bike.

The OUTRIGGER attaches to the LEFT side of the bicycle frame at 3 points, and holds a wheel that rides along the opposite rail. This keeps the railbike from tipping over, so long as YOU keep your center-of-gravity slightly inboard, on the OUTRIGGER side of your bike. I mount the OUTRIGGER on the left so there is no interference with the chain drive.

If you have any choice in the matter, I recommend you choose a lady's bike. When you are riding your bike along a rail, you are 7 inches higher off the ground than normal. Most people do not have an inseam measurement 7 inches greater than normal. Figure it out!

I also recommend the old style 3-speed bike rather than those with 5 or 10 speed derailleurs. Grass and weeds tend to get caught more easily in the latter. I carry along a short piece of coat hanger wire, and stop at necessary intervals to clean the vegetation out of the derailleur and rear sprocket. The old 3-speed shifter does not collect crud as quickly. A chain guard is also recommended.

These plans represent an evolutionary design. This means the design was improved over time as new problems came to light. The design presented here represents the final version in a succession of better and better designs. I built my first railbike back in the late 50's. I am not saying this design cannot be improved. But I will guarantee, you can make many changes that will cause problems that will not be apparent until afterwards.

If you are one of those people, like myself, who must "improve" everything he touches, follow my plans EXACTLY the first time around. This way you will be able to tell whether any later "improvements" really make things better.


It would seem so. I have been building and riding railbikes here in the Adirondack mountains of northern NY since the late 50's. There is something about railbiking that is worlds beyond merely riding a bicycle, and I love it. My wife loves it. My father loves it. All my friends love it. What makes RAILBIKING so much fun?

Perhaps the fun comes from doing something wild, not done by many others. I am sure there is more to it than just that.

Railbikes are self-steering. You are free to look around and enjoy. Those iron rails winding off into the distant unknown can provide hours of delightful excursion. They often lead through wilderness unexplored by most. You set the pace, so have plenty of time to soak up the scenery.

My favorite abandoned railroad goes right past my home. In spring everything is coming alive. Summer brings the wild growth here in the east that can almost bury an abandoned track. Curious wildlife appear everywhere. In fall, the colors, and their reflection in the many lakes and beaver ponds, is almost overpowering.

This is not to say railbiking is without mishap. Railbikes are mechanical contraptions. Parts loosen, fall off, or break, as is their nature. Even more exciting, if I dare use that word, railbikes occasionally 'de-rail'. This is railbike talk for "the blankity-blank bike came off the track."

My wife's sister got so carried away looking at autumn leaves she leaned away from the outrigger. In slow motion, she fell into the bushes and scratched herself on a spruce stubble. She got back up with a very foolish smile on her face. Be careful.

Small trees and bushes growing close to the rail can snag your foot, jerking the bike off the track. Sometimes a sudden stop will make the rear wheel skid right off the rail. You bounce along on the ties, and come to an ungraceful stop.

A good railbike design will greatly increase your enjoyment. The quickest way to a happy experience is to pick a design with a history of success, and go with it.

The Bentley RAILBIKE is a very good design. No welding is necessary. My front wheel guide makes use of side rollers. This gives you precision steering, minimal friction, and almost no noise. I use a simple handlebar lever to raise the guide slightly for crossings, or full up for normal bicycle riding. My adjustable height outrigger is an extremely rigid geometric structure that is simple and lightweight. The outrigger has excellent ground clearance to avoid brush. Pull 3 pins, and the outrigger comes completely off and folds.

Whether or not you choose the Bentley RAILBIKE design, welcome to the unique sport of RAILBIKING.

Mount Arab Lodge & Cottages

And if you find yourself in the Adirondack Mountains of upstate NY, be sure you get off the rails long enough to climb Mount Arab. It is a relatively short hike to the summit with spectacular views of the surrounding Adirondack Park. From the trailhead off the Mount Arab road you will find it to be an easy climb on a well maintained trail, even for young kids. Enjoy the views from the summit, and even better views from the renovated fire tower. The volunteer organization, Friends of Mount Arab (FOMA) maintains the trail and facilities at the summit. FOMA employs a summit steward who is available during the summer months to answer questions and offer free entry to the renovated observer's cabin outfitted as a small museum. It makes a great destination for a family picnic. You will even find a 5-star outhouse, but be sure to bring your own water, and carry down everything you carry up. You will even score one for the 'Adirondack Fire Tower Challenge'.
