Electra’s big news at Interbike was the release of their Townie Go! e-bike:

This pedal-assist bike, featuring SRAM’s E-Matic System, seems like a no-brainer for the urban bikes juggernaut. When we received the press release on the Townie Go! prior to our trip to Las Vegas, we wondered, “why didn’t Electra jump on this sooner?” A pedal-assist kit seems the perfect fit for the Townie. In any case, we’re glad to see Electra got into the e-bike market with this model. It’s available in men’s and women’s versions, with color-matched fenders, dynamo front hub, cargo rack, and a lot of other utility-friendly features.

We didn’t get a chance to ride the Go! out in the Paddock…we simply ran out of time. Hopefully we’ll be able to get our hands on a tester to share with you at some point.

Remember those Motiv e-bike spy photos we showed you a couple weeks ago? Well, we got to try the new Motiv Shadow out in person at the e-bike paddock just outside the Mandalay Bay Convention Center.

Motiv’s goal is to produce a pedal-assist e-bike that is a bit more stylish than other offerings, and we think they’ve succeeded — the Shadow takes many of its styling cues from the hot urban cycling market, including deep V wheels and color-matched decals, cable casings and other accessories.

The Shadow will be available with the choice of three battery types: 36V, 36V Long Range, or a tire-smoking 48V. Those batteries are coupled to a rear hub 500 watt geared brushless motor. The bike was a blast around the paddock area!

Motiv also had a dashing hot-pink e-cruiser for testing:

Stay tuned for an upcoming detailed review of the Shadow; RL took delivery of a tester the other day and is enjoying zipping around the streets of SoCal as we speak!

Three years ago when the UCI began to allow disc brakes for cyclocross racing, it opened a floodgate — a number of manufacturers rushed to adapt discs for road/cross disciplines. Quick advances in brake assemblies, frame fittings and forks, hubs and all the other attendant bits occured. Still, many people wondered if brakes were really needed for road bikes…and if mechanical (cable-actuated) brakes were up to the task. A couple boutique manufacturers developed mechanical-to-hydraulic adapters, such as the TRP Parabox, among others.

And that set the big manufacturers to putting their R&D muscle behind the idea of hydraulics for the road…but how to fit a master cylinder into the shifter body? It took a couple of years before it was ready, but things are finally starting to make it to market.

SRAM came through first with the “Hydro R” setup in two versions: RED for the well-heeled, and the S-700 for a somewhat more affordable option. The master cylinders are contained in the brake/shift lever bodies, and here’s the really interesting thing: they come in disc OR hydraulic rim brake options.

Forgive these somewhat awkward photos, but SRAM’s display made it difficult to get a good shot of the brake options. Check SRAM’s website for all the lurid details and better product images.

Over at Shimano, things are not quite ready for release. They had prototype Dura Ace Di2 hydraulic brakes/shift levers on display, and they felt good in the hand. They’re not scheduled for release until spring 2014, according to one of the Shimano techs I spoke to. Visit Shimano’s site for more details on the brake systems they will offer for the road.

Here are the shift levers with master cylinder hidden within:

And the brake bodies/discs as installed on a road bike:

The brake bodies and discs borrow technology from Shimano’s mountain groups, namely the ICE heat management system. Road discs can get extremely hot during prolonged descents, and that is the Achilles Heel of hydros, according to a number of sources. Shimano’s ICE system should help alleviate heat-induced brake fade.

I asked the Shimano tech if this hydraulic wizardry would trickle down to more affordable options for “regular folks” who can’t afford Dura Ace/Ultegra. Alas, Shimano plans only to offer hydraulic discs on their two upper-end Di2 groupsets…not even mechanical Dura Ace will be graced with a master cylinder setup. The reason for this is that they wanted to maintain the existing Di2 lever shape without a “unicorn bulge”, according to the tech I spoke to. SRAM’s shifting assembly and the master cylinder together take up a lot more room and necessitated a lever redesign on their end.

Finally, for those of you who use other components, or dig your current brake/shifter setup, there’s hope for you. TRP has unveiled their HY-RD system, which is cable-actuated and has the master cylinder mounted to the brake body itself. TRP claims this HY-RD system will work with any current mechanical shifting system.

TRP also still offers their Parabox adapter system.

We’re curious — are road disc brakes in your future? Any thoughts on mechanical vs. hydraulic? We’d love to hear your thoughts/gripes/concerns/WTFs. The technology still has a bit of refinement to go, but it is great to see the big component makers getting behind this new application for hydraulics.

We ran into our pal JT at the Serfas booth today — and he was happy to show off a variety of commuter-friendly accessories.

The handsome JT:

A HUGE array of headlights in various outputs:

A matching array of taillights and front/rear light combos, including some with flexible mounting options:

Even more taillights:

Here’s a great headlight (to be released soon) where the battery pack doubles as a powerful taillight:

Serfas lights are known for their true lumen outputs. The light pictured above is rated at 1000 lumens, and when Serfas claims an output, that’s what you get — no fudging the numbers like other companies do.

Need to light up the night on a dark commute? Serfas offers this 2500 lumen monster, complete with bar-mounted remote control!

There were tons more accessories for the commute and for the home shop. Take a look at the wide variety of floor pumps and travel pumps Serfas offers:

There’s a lot of Eurobike coverage all over the web right now…tons of new bikes and parts being revealed in advance of our own Interbike visit in a few weeks.

Almost all the coverage I’ve seen has been racing-oriented — new race bikes, new racing kit, new racing components. What about us commuters? What’s new for us?

One thing that DID catch our eye, thanks to the good folks at Bike Biz, is a clever new way to deal with fancy work duds. Do you happen to work in an office where formal attire is required? Struggling to juggle your bike commute and your need to wear a suit? Enter the Freefold:

Presumably, the Freefold works on business suits/attire for men AND women.

There are a couple of kludgy bags on the market now that purport to make suit-carrying easy…and while they work adequately, this Freefold system seems very simple and VERY versatile (you can fit the folded assembly into any messenger bag, backpack, or pannier). This might be just the thing suit-wearers have been looking for!

We’re going to reach out to the Freefold people and see if we can run into them at Interbike. Who knows, we might be able to score a test version to show you.
