Bacchetta bikes in Northern California

AlphaBENT is now selling Bacchetta recumbent bikes!

With the shop fairly saturated with trikes, we have found that we haven't been adequately serving the two-wheel recumbent market.

We're taking immediate action to resolve this issue with new Bacchettas now gracing the floor of the shop.

Bacchetta has established itself as a premier manufacturer of fine recumbent bikes and secretly we've long glanced enviously at any of these beauties.

Time to stop casting sideways glances and enjoy the simplicity and speed of a good high-racer.

ICE Running Improvements / 2014-2015 model-year changes

One of the sillier things we've inherited from the auto industry is the concept of "model-years". The "model-year" is a fabrication arbitrarily used by the auto-makers to make their own products prematurely obsolete. By making their own cars obsolete, they create a perception among consumers that the older car versions are somehow inferior to the current model, and this drives [pun intended] consumers and dealers to pursue a never-ending cycle of buying and selling -- forever falling behind the curve of endless "improvements"... more and more thneeds which everyone, everyone needs.

Thankfully, the fine people behind ICE do NOT think in these terms. At ICE, the end of the year is just that, and when they have a new improvement, they just put it into the pipeline and it pops out magically whenever the next batch of parts get manufactured.

For this reason, we see a steady improvement in ICE trikes, and yet since the improvements interleave into the regular production cycle and the ICE people are so modest they see improvement as part of the job rather than something to trumpet far and wide, there is little attention paid.

This article is to bring much overdue attention to some really fine improvements which have found their ways into ICE trikes just in the past 1/2 year:

  • ICE trike steering dampingSteering damping: The ability to introduce dynamic friction into the steering system is quite useful. In engineering, this is used to dampen systems that might otherwise have resonant oscillation. In trikes, this resonance is called "shimmy". Over the years, we've seen fewer than one handful of ICE trikes with any user-reports of shimmy, however, there have been a couple of bugaboos that would have been resolved much more easily if we had been able to just tighten up the damping in the steering system.

    Now, ICE trikes have steering damping. Look for the little set-screw on the handlebar pivot.
     
  • Chain-tube restraint: On trikes, the chaintube tends to get pulled slightly forward on the drive-chain and slightly backward on the return-chain. For this reason, something needs to restrain the chaintube to keep it from migrating forward or backwards. On an ICE trike, the return chain tube is held with a small plastic clamp at the idler-pulley bracket. The drive-side chaintube, however, is separated into forward and aft sections. ICE drive chain-tube retention crimpsThe forward tube is restrained using the same plastic clip, but the tube is held loosely to allow it to move with changes in the front gearing, a flare at the aft end of the tube has the dual function of guiding the chain into the tube gracefully while simultaneously preventing the tube from sliding forward through its loosely held clamp.

    This leaves the aft drive-chain tube and ICE has long restrained this tube with a perfectly placed stainless-steel crimp (crimped vertically to allow perfect chain passage). Unfortunately, with many cycles [pun] and lots of use, the crimp can loosen unexpectedly allowing the tube to move forward into the idler pulley. This failure, though rare, is surprisingly difficult to resolve without a lot of duct tape.

    ICE now make the aft chain-tube with a double-crimp.  Thank you, ICE-people!
     
  • Quick-release seat clamps: For an eternity, ICE seats have been held at the forward point by a steel cradle that is part of the frame. The cradle is semicircular, allowing the seat frame to rest in it when placed from above. A simple plastic ring kept the seat from moving upwards in the unlikely event of upward force. For a while, ICE used a quick-release lever to allow the plastic ring to be loosened and tightened rapidly with no tools. However, it was too easy for the lever to come loose and fall off. Since the plastic ring is only a retainer rather than a structural component, a missing retainer might not be noticed for a long time and by that time, the lost lever would be long gone -- left behind on the side of the road. ICE quick-release seat retention clampsEventually, ICE gave up on the levers and started using plastic thumbscrews with a retention nut. The retention nut kept the thumbscrew from getting lost, but the plastic thumbscrews took an extra ten seconds out of your day when you actually took the seat off to fold it.

    Enter the new quick-release seat clamps.... No longer made of mere plastic and sporting a long positive-action quick-release lever, these are seat retention levers for the long-term. Now, the seat clamps down and actively holds the seat in its cradle. Now, the lever releases in a snap. On the flip side, the lever pops into locking position with an active click and you know you are set to roll! Nice job, ICE!

Azub introduces "optional" hinge technology for 2015

To fold, or not to fold... this is the question.

No doubt, the ability to fold your trike or bike, particularly, the recumbent ones, can be a tremendous asset in getting it from point A to point B. On the other hand, who wants to fold something if they don't have to, much less spend the extra money on folding mechanisms and including extra weight that may be unnecessary.

Azub is introducing a new system for 2015 that defaults to being "take-apart". Separately [pun intended], a hinge can be bolted into the middle of the take-apart joint converting it the take-apart trike into a folding trike.

Rohloff lacing for ICE

Left-dished wheel with non-dished Rohlloff Speedhub!

In the recumbent world, we get to rewrite the rules. ICE and Greenspeed have designed trike frames with offset rear forks/ triangles to accept non-dished, left-offset wheels. This allows use of symmetrical lacing patterns with offset hubs, resulting in stronger wheels to withstand tricycles' higher sideways forces.

However, as a recumbent trike customization specialist, it introduces a quirky problem: the super high-end Rohloff Speedhub must now be dished the wrong way in order to line up properly. Dishing the wrong way strikes us as WRONG.

AlphaBENT has been experimenting with wheel lacing techniques to resolve this problem and this answer presents itself:

a Rohloff wheel laced with all spokes left-wise to offset the rim to the left for proper presentation to the ICE rear fork while retaining the benefits of symmetrical lacing...

And, it looks totally cool! You don't see a wheel like this every day.

NeoDrive - German electric-assist for recumbent trikes

22 October 2014, Sacramento, CA: AlphaBENT is shipping its first NeoDrive electric-assist retrofit kits.

For the past 5 weeks, AlphaBENT has been sourcing the German-engineered NeoDrive electric-assist systems to fit onto most of the trikes in the recumbent market. The first two kits have shipped this week for installation on ICE and Catrike recumbent tricycles.

The NeoDrive is the same system promised by ICE for the 2015 model year and is pictured prominently in the 2015 ICE catalog. The NeoDrive is rated at a nominal 250W with peak power output of 600W. Coupled with a high-capacity 15.5amp-hour lithium-ion battery, the NeoDrive is expected to be capable of tremendous distances between charges.

How far that is has yet to be determined and will depend on factors such as boost setting and rider behavior. Distances of 60-80 miles per charge are expected. More concrete numbers will be forthcoming. Pricing for a 250W system with 15.5Ahr battery and associated mounting hardware is approximately $2650. This system is drop-in compatible with standard configurations of ICE, Catrike, and HP Velotechnik recumbent trikes -- meaning that no major changes to other componentry are needed. Unlike other hub-based electric-assist systems, the NeoDrive retrofits can be fitted with quick-release axles facilitating wheel changes and tube and tire repairs.

The NeoDrive is a torque-based pedal-assist system, meaning that the system measures rider pedaling force and amplifies that force without the need for external throttles. Its motor occupies the under-utilized left-side of the hub to reduce rotational inertia. The NeoDrive is made with an external freehub body allowing use of the standard 8, 9, and 10-speed cassettes predominant throughout the recumbent trike industry.

All of these factors weighed into the decision to carry and support the NeoDrive brand at AlphaBENT.

New Products: ICE introduces full and rear suspension w. 26" drive wheel

St. Charles, IL: At Recumbent CycleCon 2014, Inspired Cycle Engineering (ICE) introduced its new 26" drivewheel suspension.

The Sprint 26-RS brings the efficiency of a 26" drive wheel to rear suspension comfort, reducing the comfort vs. speed tradeoff.

This new rear-fork system will be the underlying technology of two new ICE models: the Sprint 26-RS and the full-suspension Sprint 26-FS.

More later... Here are some pictures for now.

Azub recumbent technology

Azub manufacturers solid recumbent bikes and trikes in the Czech Republic.

Everyone agrees that Azub marches to their own beat and that, different as it is, it makes its own style-sense.

Take, for instance, Azub's devotion to thumb trigger shifters. Everyone else in the recumbent industry rejected the idea long ago, but not Azub. Instead, Azub steadfastly puts thumb trigger shifters everywhere they can. The cables fly up, loop around and get routed into the top of the handlebar, but, you know what? It works! These shifters have dominated the mountain biking industry because of their fantastic ergonomics and Azub owners get that benefit.

Take also, for instance, the innovation of an optional folding hinge. Only Azub makes take-apart cycles that allow you to insert a hinge should that functionality appeal to you.

Take also, for instance, the Azub tail. Look at the Azub lineup and you are sure to notice the tails. Oversize aluminum tubing forms the backbone of many Azub cycles and then a little stub stick out in the back. That stub is more than a fashion statement, it is the mounting point for the rack.
