Quick Overview
The Pony Express 2100 is the first motorized liquid gas cylinder cart with automated loading and unloading. Built by Electro Kinetic Technologies, it picks up a large liquid cylinder, often called a dewar, and sets it back down without the operator lifting, tipping or steadying the load by hand. That removes the back strain of moving cylinders and the finger and hand injuries that happen when a heavy cylinder is levered onto a manual cart.
The patent pending drive system moves cylinders up to 850 lb on flat, inclined and rough surfaces at walking pace. The ergonomic cart maneuvers in tight spaces, so it threads through storerooms, elevators and corridors, and the built in braking prevents loss of control on sloped surfaces.
Safety is engineered in at every level. Regenerative dynamic braking brings the cart to a controlled stop at any speed, an electro mechanical parking brake locks it when parked, and a horn and emergency stop button sit at the operator station. Automatic sleep mode conserves the battery between deliveries, and the on board UL and CSA listed smart charger runs on any 100 to 240 VAC outlet. A charge covers up to 10 miles of operation.
Hospitals use the 2100 to deliver liquid oxygen, labs and fill plants move nitrogen and argon dewars, and manufacturers run it wherever large liquid cylinders travel. Like every Pony Express cart it is designed and manufactured in the USA with a heavy duty welded, powder coat painted frame and a 2 year warranty on the frame and drive system. Need the smaller cart for K size high pressure cylinders? See the Pony Express 2010.

The cart covers up to 10 miles of operation between charges. The on board UL and CSA listed smart charger accepts 100 to 240 VAC, so it tops off from any standard outlet, and automatic sleep mode conserves power between deliveries.
What cylinders does the Pony Express 2100 carry?

Options & Upgrades
Frequently Asked Questions
What is the difference between the 2100 and the 2010 cylinder delivery cart?
The 2010 is the compact cart that takes a single dewar or up to four K size high pressure cylinders and the operator loads it by hand. The 2100 is built for the large liquid cylinders only and adds automated loading and unloading, so the cart itself picks the dewar up and sets it down. If your team moves dewars all day, the 2100 removes the lift entirely.
How does the automated loading work?
The operator positions the cart at the cylinder and the cart handles the loading and unloading. Nobody tips, walks or wrestles the cylinder by hand, which is where most hand and finger injuries in gas handling happen. Call us and we will walk you through the loading sequence for your cylinder size.
Who uses the Pony Express 2100?
Hospitals delivering liquid oxygen, laboratories and gas distributors moving cryogenic dewars, and manufacturers handling liquid nitrogen or argon for process work. It is rated for industrial, medical and commercial use.
How does the 2100 prevent rollback on ramps?
Regenerative dynamic braking gives a controlled stop at any speed and an electro mechanical parking brake locks the cart when it is parked. Together they hold a loaded cart steady on inclines.
Is the Pony Express 2100 made in the USA and what warranty does it carry?
Yes. It is designed and manufactured by Electro Kinetic Technologies in Germantown Wisconsin and comes with a 2 year warranty on the frame and drive system.

Does Medicare, Medicaid or private insurance help pay for the Pony Express 2100?

Great Experience!
Super helpful team in helping us make a decision. We needed a scooter that we could modify to carry our 2 Jack Russell’s at trials. This scooter worked out perfectly. Please let them help you. I’m sure there are bigger companies, but I felt we got such personal attention. It was an amazing experience. Delivery was just a few days. Remarkable!

Auto Fold
I needed a mobility scooter that was auto-folding, but not overly engineered where problems can arise, was not too heavy to lift by myself, would easily fit in the trunk of my car, and not be overly expensive. Wishful thinking I thought. Until I discovered the MOJO on my computer. This scooter ticked all my boxes, and more. It is comfortable, well built, is easy to charge the batteries without having to bend down to remove them, and even if you do want to remove them they are accessible from the standing position. the tiller is fully adjustable as are the arm rests, the folding/unfolding functions are easily initiated, and the axle release is easily achieved. A well engineered piece of kit. Now, for the customer service: I can honestly say that I have never come across anything like it; it is absolutely perfect. The gentleman I dealt with 'bent over backwards' to help me without pressuring me into a purchase, and to ensure I was buying a scooter that was right for me. Because I live in New Zealand I knew I was creating a lot more work for him, but he never complained. This and my MOJO are very much appreciated. I am very thankful for the day I first saw the MOJO on the internet. I I now own my very own MOJO.

We are so pleased with the Scoota Trailer we ordered through Heavy Duty Mobility. We dealt with Raphael who could not have be nicer and more helpful. He stayed in close contact letting me know when the manufacturer received the order, when it was complete and when it shipped. The customer service was second to none. It was obvious in all communications with Raphael that he genuinely cared that our son's needs were met with this trailer for his new powerchair. I highly recommend going through Heavy Duty Mobility when ordering equipment for yourself or your handicapped loved ones.

Heavy Duty Mobility did a fine Job.
Heavy Duty Mobility did a fine Job matching me up with the besr mobility scooter to meet my needs. The Afikim S-3 is a high quality piece of equipment. It operates as advertised. It maintains it's speed while ascending the hills in the small town, where I live. Heavy Duty Mobility was by my side throughout the entire purchase process. Even after I took delivery of the fine S-3 scooter and needed to have questions answered about the machine. Jon Fisher Cedarville, MI

I was looking for a scooter for my mother. I researched it online and found some sites that were selling the scooter for the same price. Heavy duty mobility was willing to beat the price as they had a 5% discount. They were also. Extremely kind and helpful. They answered all my questions and what they did not know. They contacted the company to find out and got back to me the same day. They kept me in the loop with shipping and also reached out to me to confirm receipt and to make sure everything was correct and working properly. Very impressed

Top shelf, customer service,
Found the type of Scooter. I wanted to buy online not everyone has the kind of scooter. I have . Talked to Raphael Perlmann about the scooter I wanted. I was a little hesitant at first because they were from Florida. After talking to Raphael I felt a much more comfortable about the idea of having a scooter shipped all across the country am in Seattle WA.
The scooter arrived,in shipping and had a torn seat. Ops Raphael took care of the problem got me a new seat ASP negotiated with the makers of my scooter.for me.
Couple months into having my scooter. I had an issue with the wheel making a noise..
Called my dealer Raphael he worked tirelessly negotiating with the maker of the Scooter to make sure the issue got fixed .
Would’ve loved not to have any issues with my new scooter, but knowing Raphael was on my side, helping me anytime there was an issue to get the problem fixed was a huge blessing.
Raphael Perlmann Has restored my faith in Customer service .
So many companies sell your product and then they don’t care they got their money !
Not that way at heavy mobility scooters store .
I have seen that this company and Raphael Perlmann cares about their customers after the sell.
I will recommend to my mother and any other family member, and friend to order a scooter from Raphael Perlmann ..:
His care and consideration for me and my Scooter has definitely restored my faith and Customer service .
The quality of customer service I receive from him is a wonderful change from the type of customer service I get from businesses I work with and give money to every month .
Other companies couldn’t learn something from this man and heavy mobility Scooter about Customer service .
Thank you
Raphael Perlmann For the caring you show your customers .
Top shelf customer service .

They are very professional, they listen to what you would like to have, and they may make suggestions, but the decisions are up to you.
The person I talked with was very professional.
He knew what products I may like, but in the end it was my choice of what to buy, or not buy.
There was no pressure, just suggestions I appreciate people who don't pressure you into buying something.
