Electric-assist torque anchors

A hub-driven electric-motor such as Bionx, Neodrive, or GoSwiss needs an anchor point that is physically fixed on the recumbent trike or bicycle, so it has something to push against. Without this anchor point, the hub would simply spin when activated with electricity.

With the anchor point, the hub can convert its spinning force or torque into forward force moving the trike forward. Every manufacturer has a unique spin (pun intended) on how this is best implemented, and each manufacturer calls the anchoring device something different. Bionx calls them "torque collars" whereas GoSwiss calls them "torque arms".

To complicate matters, Bionx has a gravity-sensitive strain-detector inside the hub. This means that the Bionx hub must be fixed in the recumbent tricycle at a particular orientation or it will not accurately sense the rider's pedaling force. Therefore, Bionx originally designed a torque collar wedged itself in place at any angle and it could be positioned differently to fit all of the plethora of different bike dropout profiles in existence.

This was a very simple and infinitely-adjustable design, and its only flaw was that removing and repositioning the torque collar required a special press tool and each shop preparing aftermarket Bionx electric-assist systems had to purchase the special tool.

After a while, Bionx redesigned the torque collar to go on and off with no special tool and it would key into a particular position with a flat edge of the torque collar fitting perfectly onto a flat edge of the motor axle. This design made it much easier to get the torque collar on and off, but it meant that a different torque collar had to made to fit each of the different dropout profiles / angles. All of a sudden, shops that used to be able to pop a torque collar off with the special tool were now required to maintain an extensive inventory of these torque collars, each holding the motor at different angles.

The standard torque collar included with a Bionx 350W electric-assist is a 27-degree torque collar. However, some recumbent trikes such as Catrike always require a different torque collar.

We recently came across a pair of these Catrikes that had Bionx systems installed without the correct torque collar. The tip-off was how much force it took to get the axle nuts off. When we pulled the wheels of each trike, we found that the unscrupulous dealer had filed away the flat keyed part of the torque collar and re-installed the torque collar with no torque anchor. To keep the axle from rotating under load, that dealer had had to tighten the axle nuts to an amazingly high torque!

GoSwiss and Neodrive electric-assists do not have the same gravity feedback as Bionx systems, so the orientation of the axle doesn't matter. Both of these European systems use a splined interface that allows the torque arm to be angle however it works best for the physical shape of the cycle frame.

Bionx electric-assist on Bacchetta A26 recumbent bike

The Bacchetta A26 is the successor to the Giro ATT premium touring / commuting recumbent bike model. It is one of the fastest touring bikes made and A26 owners usually struggle to keep under a 15mph bike-path speed limit. 

On the open road, though, if you are commuting, you might just want to add an electric assist to ease the commute. Bionx offers a nice solution for this with a 350W rear wheel hub-based motor.

The standard interface to Bionx systems is to just pedal. This is because Bionx motors have a strain sensor that detects when you are pedaling and how hard, and the system multiplies your effort turning you into a Bionic Person.

However, it is always problematic to mount a battery, and it seemed moreso on the Bacchetta because we didn't want to force a rack onto it and we wanted to keep the weight low and central. At AlphaBENT, we have devised a nice battery mount for Bacchetta bikes that allows the battery to hang suspended just under the idler pulley. Advantages are:

  • plenty of clearance
  • low, central weight distribution
  • clearance for all leg and foot movement
  • universal design should work on all Corsa and Giro Bacchetta recumbent bikes.

If you are thinking of electrifying your Bacchetta recumbent bicycle, bring it on by and get it installed by Northern California's Bionx experts.

HP runs out of US-available Gekko FX-20 recumbent trikes

Surprisingly, HP Velotechnik has run out of supply of its US-available Gekko FX-20 folding recumbent trikes for 2017.

Demand must have outstripped supply as dealers looking for Gekko FX20's in HP's US warehouse have been turned away empty-handed.

Gekko FX-20 trikes are some of the tightest-folding recumbent trikes in the industry and have all 20" wheels. This configuration is a bit slower than the 26" larger version of the FX20, but it folds up tighter and doesn't require a supply of two different tire and tube sizes.

HP Velotechnik maintains a supply of US-available Gekko FX-20's in their US warehouse and because these are shipped directly from Taiwan without touching German soil, they don't some with the same price constraints as the same model coming out of Germany. Gekko FX-20's are still available when custom-ordered out of Germany, but come at a $600 premium to cover the additional duties and international air-shipping.

This puts the price of a Gekko FX-20 shipped to the US from Germany on par with the base price of a Catrike Trail, or a base-model ICE Sprint-20 or Adventure-20.

The Catrike Trail has a similar folding system, but is U.S. made with a higher component specification. ICE recumbent trikes are of a modular design with each trike priced depending on configuration. ICE trikes are custom-configured in England and air-shipped to the U.S.

HP anticipates having Gekko FX-20's in stock in America for 2018.

Day-6 semi-recumbent / forward crank bikes back in stock soon

Day-6 semi-recumbent bikes will be in stock again soon. Production delays have made Day-6 bikes a limited-availability commodity for the past two months, but the wait is almost over.

AlphaBENT expects a new shipment of Day-6 forward crank bikes on Friday, July 28, 2017, but it's not clear how long they will last.

Some customers have been waiting two months, and other potential buyers have had to exercise their patience waiting for the delays to end.

Full stock of Dream-24, Dream-8, and Samson Day-6 bikes will be ready for a test-ride soon.

Time ticking against Azub price increases

In an unconventional move, Azub is raising prices in mid-season.

On Monday 15 May 2017, Azub prices will increase by 2-5%. 

Full-service shops like AlphaBENT are taking last-minute orders through the weekend of 5/13-14 of 2017. Some Azub trikes like a full-suspension Ti-FLY with Pinion 18-speed transmission can be quite expensive, so a 5% discount is a significant difference.

Of all the recumbent trike manufacturers, Azub is the only one offering Pinion transmissions.

Azub has also announced a new configurator to help buyers customize configurations and place orders through top dealers like AlphaBENT with a minimum of hassle.

Recumbent Tandem Rider Magazine goes online

Recumbent Tandem Rider (RTR) Magazine has been covering the recumbent industry these last many years since the beginning -- and now, for the first time, the print copy of RTR magazine is available online.

RTR magazine publisher, Charles Coyne, is a constant shadow monitoring the comings and goings in the recumbent industry. He has also taken the initiative of creating the Recumbent CycleCon (the industry's only trade show in the United States).

As regularly as clockwork, stacks of RTR magazines have arrived in leading recumbent dealer shops like AlphaBENT. These unique magazines have been a key source of product information, reviews, and adventures dealing exclusively with recumbents and tandems.

Recumbent Tandem Rider Magazine will continue to be available in its print version and physical copies of the latest issue can be picked up for free wherever they were available before. But, now, the exact same magazine can be viewed online at RTRmag.com

Recumbent trike racks 1/2 off

[Disclaimer: This item was posted on April Fools Day, 2017. It is not to be taken seriously, though, perhaps, half-seriously. The rack and the trike are real and not Photoshopped. The trike is a Terratrike (perhaps an older Tour) and the rack is based on HP Velotechnik design.]

Today only, AlphaBENT is selling recumbent trike racks that are half off.

These racks are for trike owners who know that "less is more".

They are specially designed for non-touring trike-riders who have half a mind to take something with them, but aren't quite sure. The novel design leaves one side available for mounting dynamos and other accessories.

Manufacturers benefit from the 1/2-off concept by only having to design half of the rack and production is half as fast.

The first partial prototypes are in and AlphaBENT is selling them to test the market.

The new concept ushers in an era of fractional sales of fractional goods in the Fractional Economy.

Adherents of the Fractional Economy Concept say the economy gets a strong stimulation because recumbent trike buyers can purchase their trikes as they can afford to.

"I can see a day coming when people will buy 60% of a trike one month and then buy 15% more when their next paycheck comes in.", said AlphaBENT owner, Hugh Kern, "I'm only partially sure that this is going to take off. A lot of people have been telling me that this is a half-a__ed idea, but, I decided to just run with it."

Eon green back in Catrike color lineup

Catrike has resolved its production issues for the eon-green color and is now producing recumbent trikes in this color again.

One of the few manufactures doing its own in-house frame production and powder-coating, Catrike has extraordinary flexibilty in producing different colors and in shaking up its color lineup. However, the dark side of this is that when some sort of production or supply glitch hits, a popular color like eon-green can simply disappear overnight.

This is what happened to eon green in October 2016, and it took some months for the issues to get resolved.

For now, eon green is available again on all Catrike recumbent trikes.

Catrike discontinues Hyper-yellow and Eon-green recumbent colors

Catrike has discontinued its popular Hyper-yellow and Eon-green colors due to supply issues with the green powder-coating ingredient used in both colors.

Because Catrike builds and powdercoats its own frames in-house, they have tremendous flexibility in making production changes on the fly. They also enjoy experimenting with powder combinations to make unique colors.

Hyper-yellow and Eon-green were the result of this experimentation and both relied on the same green ingredient component. However, late in 2016, there was a glitch in the supply of this green powder.

Now, the few remaining new Eon-green and Hyper-yellow Catrikes will be the last ones.

Other manufacturers using standard European RAL colors can produce a hyper-yellow equivalent by using an RAL equivalent.

(Note: some day-glo / flourescent-style colors can have long-term fading from exposure to the sun.)

Announcements

Catrike Road-AR quietly introduced -- full-suspension recumbent trike

Catrike recently removed the Road rear-suspension recumbent trike from its model line-up and replaced it with a full-suspension Road-AR.

The change was made with little or no notice to dealers and potential buyers, and has taken Catrike aficionados a bit by surprise.

For Catrike, with the main development work on the new front-suspension spindles behind them, it was probably a very easy change to make.

Catrike's new front suspension spindles have different engineering constraints, so a straight-across front-suspension upgrade path does not exist for end-users. But, with the manufacturing process completely under their own control, Catrike can easily change tubing specifications to meet the needs of the new spindles, and this seems to be what has happened.

The pricing of the new model is interesting. At $3550, the new Road-AR is $400 more than the Road model it replaced, but $600 less than its nearest comparable Catrike option -- the Dumont.

And, $3550 for a full-suspension recumbent tricycle with these specifications is extremely competitive. By comparison, HP Velotechnik's full-suspension trike with 20" rear wheel, the Scorpion FS-20, starts at $900 more with a very different set of components.

Comparing such models is difficult, though. With its integrated sway-bar, and indirect steering, HP's FS-20 is undoubtedly more expensive to build and the suspension handles bumps quite differently.

It is also important to note that the Road is NOT a folding trike like the Catrike Dumont and the HP Scorpion FS-20.

Top-level recumbent dealers like AlphaBENT expect to have Road-AR recumbent trikes in stock by the end of May.
