I'm picking up a new Cripple Cart to keep down in the Lower 48 at Brian's place.  When we come to Seattle you gotta do some modifications on it to soup it up!

A battery pack with one extra cell in the series stack should give peppy response over a reduced range it the electronics don't complain.  A custom charger would be needed but that should be pretty simple to do.

New Priority Embark electric bicycle features Bosch powered belt driven CVT

@MicahToll



Priority Bicycles has just dropped the veil on their new electric bicycle, the Priority Embark.

The new electric bicycle removes most maintenance-heavy components typically found on e-bikes, creating a nearly maintenance-free electric bicycle.

Priority Embark electric bicycle

Priority Bicycles’s new e-bike, the Priority Embark, features an array of high-end components. We’ve seen such high-end components on e-bikes before, but they usually cost twice the price.

The centerpiece of the bike is Bosch’s newest mid-drive motor, their Bosch Active Line Plus. The motor is designed to provide pedal assist up to 20 mph (32 km/h). That classifies the e-bike as a Class 1 electric bicycle. For anyone who wants to get exercise while still enjoying the commuting power of an electric bicycle, a Class 1 e-bike is for you.

The down tube battery, which is integrated into the frame instead of resting on top, is sufficient for 50 miles (80 km) of range. Keep in mind that this is a pedal assist bike, meaning that 50 miles is likely realistic.

A Gates Carbon Drive Belt transfers power from the Bosch motor to the rear wheel. That removes the chain and front gears, reducing the number of high-maintenance parts.

On the other end of that belt is an Enviolo Trekking continuously variable transmission (CVT). The CVT allows shifting from rest like a standard internally geared hub. However, it also provides an infinite number of intermediate gear ratios between its stops. The CVT replaces the derailleur and standard cassette found on most electric bicycles.

Hydraulic disc brakes are also included, which reduce the need to adjust cable-actuated disc brakes.

For comfort and durability, the Priority Embark also features a WTB saddle and WTB tubeless tires and rims.

According to the company, the Priority Embark is the result of four years of extensive testing of a variety of electric bicycle components. The company chose the components that combined high quality and low maintenance to create a simple, easy to use electric bicycle.

As explained by Priority Bicycles’ founder Dave Weiner:

    “Our customers have asked us about an e-bike option for years now, from the bolt-on kits to high-end luxury models, but it was important for us to design the ‘Priority version’ of an e-bike. One that empowers riders to explore new areas, run errands, or simply get to work without sweating – all in the low maintenance package for which Priority is known.”

Priority Bicycles

As much as everyone likes to hate on Kickstarters, Priority Bicycles is a Kickstarter success story. In 2014, the company crowdfunded over $500,000 and delivered 1,200 bicycles to their backers. Ever since, they’ve been working to improve their designs, culminating in this latest Priority Embark release.

The company sells consumer-direct, including with the Priority Embark.

Priority Bicycles has partnered with Velofix, a mobile bicycle repair and delivery service. Velofix will assemble and deliver customers’ Priority Embark electric bicycles after purchase.

Going even further, Velofix is also providing test rides of Priority Embark electric bicycles. They’ll show up at your door with a ready-to-ride bike for testing, though you have to live in Los Angeles, San Francisco, Boston, Denver or Seattle.

Speaking of purchase, the Priority Embark goes on sale today with a price of $3,499 (marked down from $3,999 MSRP).
Electrek’s Take

If you want a high quality, hassle-free e-bike that shows up at your door, this could be your ticket. With 7-day a week customer service and a strong record of customer satisfaction, Priority Bicycles is focusing on consumers who just want their bike to work and don’t want to deal with the mess and maintenance of traditional bicycle ownership.

Sure, the Priority Embark is expensive when you compare it to $500 e-bikes, but the price is actually quite reasonable considering the components.

Bosch motors aren’t cheap, and for good reason. They’re well engineered and worth their weight. Gates belt drives cost a pretty penny too. That Enviolo (which used to be NuVinci) CVT hub alone is a good chunk of change. All of these parts are expensive, but when combined, should make for an enjoyable and hassle-free experience.

And that’s the whole point of the Priority Embark.

While originally conceived by DaVinci and used for a while by the vehicle industry and abandoned for some strange reason; the CVT is absolutely amazing.

One gets 40 miles to the gallon in a big luxury sedan and they keep perfecting them. A true marvel of modern technology.

I can personally vouch for them and their dependability and would not consider buying a car foe myself oe any member of my family unless it had a CVT transmission.

The Nissan motor company perfected them years ago for the mass market and now everyone is following suit including the snob names like BMW and Mercedes.

Diner's, Do yourself a favor and try one out before buying anything else, the savings in gasoline alone will make it worth it.

Tern Launches Corporate Electric Cargobike Program

The Willard Street Inn, Burlington, Vermont, rents out Tern GSD bikes to enable couples to enjoy a nearby scenic bike path – the bikes can be loaded with a picnic featuring a selection of locally-sourced delicacies.TERN
Bicycle maker Tern has launched a “bikes-for-business” program to promote its GSD – “get stuff done” – electric cargobike. The Taiwanese company with international staffers and global distribution is aiming to pique the interest of hotels and short-haul delivery firms. The program – trialled with a number of small businesses already using GSDs – includes cloud-based fleet management as well as customization options, including corporate color schemes and branded fascias. The corporate program will be delivered through local bike shops.

“E-cargobikes are a great alternative for some 20 percent of all delivery vans currently operating in large cities,” concluded a recent Dutch study. The 121-page City Logistic: Light and Electric report argues that cities are being strangled by trucks and vans – and one of the solutions is for businesses to switch at least some of their “last-mile deliveries” to electric cargobikes. Most of these are long and somewhat cumbersome. Not so for Tern’s GSD – this is billed as a “compact” e-cargobike, yet it can still haul 378-lbs, no sweat.


The $4,000 small-wheel GSD is a one-size-fits-all machine, and unlike a motor vehicle it doesn’t require insurance or a license to operate.

“More businesses on bikes is something that is essential for the health of our planet,” said Tern CEO Josh Hon.

“But it’s also great for the people working in those businesses who’ll get more fresh air and exercise. And it’ll be a really good thing for dealers who can start to build a recurring revenue model for their shops.”

Vermonters like bikes. Yes, the folks in Burlington probably like e-bikes too. BUT, Vermont has real wet, slushy, messy winters. Winters here last a long, long time. Even with global warming the rainy messy mix we get makes biking a challenge. I actually did drive a pedal bicycle to a job I had parking cars at the airport (in winter) way back in 1998 for about a month. It sucked. It was slippery as all getout in winter and the cars made life rather difficult. If the young folks go for that, good for them. I'm too old for that.  :(

A Trike Electric with knobby tires makes things a little better.  This one from Z-electric is only $7K.  I may buy it in the spring.  It has a VIN number and you can license it for road use too.

Had I been in that thing when the pickup truck that front ended me drove into oncoming traffic last week I'd have been killed.  As it is I'm uninjured.  Electronics batteries and motors are all available but somebody needs to do more than slap the components together to make a solution that works.  Three wheeled electric carts are nothing new.  This one is wrapped in a light plastic shell.  That plastic might shatter in Alaska temperatures.  I'd check into what it is made of before I got one.

I've been to the factory, very nice machines.  He has clients all over the world, including Mother Russia.  It gets cold there too.  I wouldn't take it on the roads currently, I would use the bike paths.

More negative waves.  ::)

It's hard keeping a good attitude when your vacation just ended and you're back at work doing all the stuff other people were supposed to do while you were gone.

It's a joke, and one of my least favorite people ever (Margaret Thatcher) said it, but it's true.. The problem with socialism is that sooner or later you run out of other people's money.

We will surely get more socialism in some form here, if BAU lasts long enough for the Rethuglicans to swing the sentiment back to that line of thinking, and we've raised a generation of kids who will embrace it....but there isn't juice left to cover al the needs, and whatever kind of socialism we get, I doubt the military will get downsized, which is the very worst problem we have (besides climate change, I mean.).

I'd be fine with some kind of social democratic government ala Canada or Sweden....but the truth is, and I've always said, it isn't the system that's the issue as much as it is the benevolence or lack thereof of who is in charge. Our leaders, left and right, are all a bunch of opportunists who use their office for personal gain.

And...it is NOT just conservatives who do it.

That happens with capitalism also.  All the money ends up in the hands of a few rich people, everybody else runs out of money.

The only thing I don't like about Canada, for instance, is that guys in my line of work tell me that it puts a real ceiling on your earning ability. I haven't talked to anyone lately, but at one time I had somebody I trusted tell me that once you hit about 300K income, the government takes almost everything.

So it robs you of incentive. Just like it robs poor people of incentive, when working harder puts them above the poverty line so their bennies get cut.

I think in any social democracy, their are still corporate elites who beat the system. Like the IKEA guy Jim Quinn used to rail against.

In real socialism, or communism, the bureaucrats get all the goodies. Cuba is a case in point.

True. An electric all weather trike would work great here. For those who think they must drive an 8,000 pound PLUS tank to feel safe, I understand, but that is not, or has ever been, the issue with small economic vehicles. So, it is irrelevant to the subject of e-bikes. Surly's wife was saved by driving in an SUV (Subaru Forester). That does not mean, K-Dog, that these small electric vehicles (The E-Tuk sells in Colorado and is used to taxi tourists around - they also sell them for small businesses like this coffee serving model ) are not selling well AND are part of the Renewable Energy SOLUTION.

SNIPPET:


Geographically, there aren’t a lot of surprises. As this chart of e-bike manufacturing revenue by country shows, China by itself is the biggest manufacturer of e-bikes, followed by the USA and Taiwan. That last comes with a political wrinkle, however. China considers Taiwan to be part of China, while Taiwan considers itself independent. Taiwan, or the Republic of China, lost its UN seat to the People’s Republic of China in 1971, but still maintains official diplomatic relations to 16 countries and informal diplomatic relations with most of them.

Why this is interesting is that the two largest revenue firms for e-bikes globally are both from Taiwan: Giant and Merida. This chart shows the top 15 firms by estimated e-bike revenue.


here are a couple of additional points worth noting about this chart. First, the majority of firms in the e-bike market today are making less than US$100 million specifically from e-bikes. Giant and Merida, at an estimated US$170 million, are more than double the size of the next largest individual competitor. They are well-positioned to continue to dominate. Second, while most companies have a relatively limited number of models across a handful of categories, the number of variants within models is very large, especially for smaller pure-play Chinese manufacturers.

Yep. Gotta pick your spots. Might be fine for local travel, but on a highway? Not likely.
I found myself parked beside a woman who had a Smart ForTwo car last weekend. Really cute. I could not resist asking her about it. She laughed and was very gracious, said she gets that a lot. Said she loved riding it around town, and that it was a perfect commuting vehicle for in town trips. But that she would never take it on an out of town trip.

As AG noted about Contrary's wreck, when you're on the interstate and get rear ended by a drunk going over 100, you want to be wrapped in a steel cage.
