Truck Trike; A Heavy Duty Hauling Ebike

Every once in a while we see an ebike that breaks the mold.  Imagine instead of investing in a small pick up truck, you bought  an ebike large enough and powerful enough to carry a descent amount of cargo, and do so on pennies a charge.

Bill Stites is a former chiropractor turned talented designer and metal worker that is working on a new creation in one of the most creative ebike meccas in the world:  Portland Oregon. Portland is a combination of eco minded people, one of the best bike infrastructures in the country, and a hilly terrain that begs to go electric.  In fact Portland has been called “the ebike capitol of the country“. Portland is especially known for its electric cargo bikes.

Bill found a new nitch in taking the cargo bike to a new level with an electric cargo  bike large enough to make deliveries of large and heavy products. Bill thinks of it as one of the most efficient electric bikes imaginable.  The Truck Trike can carry up to 600 pounds and is designed with commercial enterprises in mind that want to reduce their eco foot print and at the same time save massive money on gas and parking cost.

Rugged Frame Lovingly Built

Each frame is hand built by hand in Bill’s Portland Shop.   It is built  of  steel to be extra strong and rigid. This is the 3rd version of the frame, and each one has gotten a bit better, stiffer and stronger. If you wonder why this ebike is so expensive, you could start with an intricate steel frame that is made in America by expert craftsman.

Propulsion system

Hub motor hi-torque

The Truck Trike uses one of the highest quality (and expensive) hub motors available which is the v2 BMC (read our review).  You can choose for your Truck Trike to have a one or two wheel powered drive. With 2 BMC hub motors, one in each rear wheel, there is a $2000 up-charge. Then you get double the torque and double the power, and double the battery.

The Truck Trike can come with one 48v 20ah battery, or 2  batteries if you go with the 2 motor system giving you a total of 40amp hours.

For the single motor system, the price is $7,850 and for the dual motor system you are looking at $9850

Unfortunately the Truck Trike comes stock with heavy lead acid batteries, but for a price you can upgrade to a lithium ion All Cell pack which I would recommend for battery longevity and weight savings. On a trike that is so heavy to begin with, forget lugging this thing up stairs etc, so running lead acid isn’t as much of a deal killer as it would be on a standard electric bike.

I would expect with 2 BMC motors you could expect a top speed of over 20mph on level ground, and can could climb just about any hill. I would expect a 20-40 mile range with the dual battery/motor system, depending on what you are hauling and how hilly the terrain.

Creative Human Input

StitesHub area

The Truck trike uses the “StitesHub” was developed by Bill for a pedal trike he designed  back in 1996.  Since he was doing primarily recumbents at the time, he felt the need to tighten up the drive system by shortening the unusually long chain.  It worked really well at separating the drive and steer forces that need to culminate to the same wheel. .
Bill  decided to use the same concept on the Truck Trike, as he wanted to simplify the overall drive systems. By fully separating the human and electric drives [human to front wheel, electric to one or both rear wheels], he eliminated the need for inter-mixing transmissions, differentials, etc. – there’s not even a cross axle in the rear.  The Truck Trike uses standard hub motors for ebikes, and so each of the rear wheels is mounted in its own pair of dropouts.There are myriad advantages to this system, including a lower floor for a lower center-of-gravity, and thus more vehicular stability.  From an engineering perspective, there is great benefit in spreading the drive stresses among several sources, rather than having all the drive forces course through one chain, for example.  Since each wheel has it’s own power source, it is easier to achieve all-wheel drive, (with the 2 motor configuration)
Also, the modular design – where the front and rear frames bolt together – was facilitated by this separation of drive systems.

Motorcycle Brakes

Motorcycle Disc Brakes

The  Truck Trike isn’t  like anything that has come before in the bike world.  While it is a “hybrid” relative to its power sources [human + electric], it also can be described as a hybrid in its overall configuration.

The front end is easily recognizable as a bike.  But the rear end – with its 600+ lb. capacity – is more like a truck.  While Bill  tried to stay on the level of bicycle components for ease of availability and maintenance, it became clear that there were no bicycle brakes – even downhill hydraulics – that were up to the task of stopping upwards of 1/2 ton of mass [vehicle+driver+payload].

Thus, motorcycle-level hydraulic brakes  were specced for the rear section.  Such technology is well-proven, and readily available. Even though they are heavier than regular brakes, on the huge Truck Trike a few extra pounds equates to almost nothing.   The motorcycle brakes  provides full confidence in the ability to stop a fully loaded Truck Trike even when trucking down steep downgrades.

The photo below shows identical wheels with a bicycle rotor on the left, and the new motorcycle rotor on the right.  Bill  designed and machined a custom adapter to mount the monster rotor on a bike hub’s standard 6-bolt pattern.

 Who Would Buy One?

The Trike Truck costs $9850 in its awd configuration.

The Truck Trike would be awesome to own for anyone except for three  huge factors #1 the cost. #2 the space it takes to park it.  #3 275 pounds makes it one of the heaviest ebikes on the planet.

The Truck Trike was designed with the business owner in mind who can actually save money by owning this  trike.  Also, it is possible that someone could base a new start up business around this Trike, for example a bicycle messenger who can deliver refrigerators, or an electric-powered  pedal cab driver, or an electric lawn care business that carts their electric lawn mowers on a Truck Trike, or a high tech newspaper deliveryman who has a helper in the back throwing out the papers while he Trike Trucks down the road. The Trike Truck is Safe, heavy duty, and clean looking, and would attract a lot of  positive attention to any business.
