Weekend project: How to build your own DIY 40 mph fast electric bicycle

Electric bicycles is a booming industry. It seems like every week we hear about another new model entering the market. Outside of a few exceptions, most electric bicycles fall in the 15-28 mph (25-45 km/h) range. That’s fine for pleasure riding, but it leaves many enthusiasts looking for more speed.

With so many people commuting on electric bicycles, the extra speed of a fast electric bicycle is a nice addition for many, allowing them keep up with traffic. However, there aren’t many commercially available options for fast electric bicycles. That’s why I decided to build my own, with the goal of reaching 40 mph (64 km/h). Read on to see how to build your own DIY fast electric bicycle.

See How Cold Weather Impacts Tesla Model 3

Cold weather impacts every EV and ICE car, but precisely, how does the Tesla Model 3 fare?

One of our most highly respected sources, Trevor Page from Model 3 Owners Club, is situated in the great white north. Trevor lives in Canada and has to deal with extreme cold weather on an almost year-round basis. He’s shared with us before about dealing with EVs in the frigid climate. Most notable is his previous take on charging and range loss in Tesla vehicles in cold temps. But, more importantly, he now has a Tesla Model 3 and he’s updated us with his observations surrounding how the cold weather may impact the EV.

There’s nothing completely compelling in this video for those that know Tesla products and EVs in general. But for those electric-car rookie reservation holders, this is surely something to be considered. Keep in mind that this doesn’t just apply to the Model 3, but any EV. Batteries react to the cold and that’s important to note. However, it’s not really bad news.

Let’s think for a minute here about the fact that ICE cars can’t be warmed up in your garage, there’s no true pre-heating function, and sometimes gas-powered cars refuse to even start in bitter temps. While EVs may have reduced range in cold weather, so do gas-powered cars. But regardless, there are many advantages to owning an electric car.

Imagine charging at home and never having to endure the cold at a gas station! Think of a car that starts instantaneously regardless of the weather. How about even heating your cold garage with your EV and having forever warmed seats and cabin previous to ever venturing out in the elements.

Let us know your thoughts and concerns in the comment section below.

2. Tesla Model 3
Range: 310 miles; 136/123 mpg-e. Still maintaining a long waiting list as production ramps up slowly, the new compact Tesla Model 3 sedan is a smaller and cheaper, but no less stylish, alternative, to the fledgling automaker’s popular Model S. This estimate is for a Model 3 with the “optional” (at $9,000) long-range battery, which is as of this writing still the only configuration available. The standard battery, which is expected to become available later in 2018, is estimated to run for 220 miles on a charge.

Audi Says E-Tron GT Will Outsprint Tesla Model S P100D

Will do so by getting “some genes from Porsche.”

And by adding “a lot of Audi genes.”

Audi says the E-tron GT will outsprint the Tesla Model S P100D thanks to a secret weapon in the form of Porsche.

Still not due until 2020, the E-tron GT will boast range on par with the E-tron SUV (248 miles WLTP) but be “focused more towards power,” according to Audi’s powertrain boss.

In order to beat the Tesla Model S P100D, Audi would need to make the E-tron GT zip from 0 to 60 MPH in well under 2.5 seconds. The P100D officially hits 60 MPH in 2.5 seconds, but timed results are closer to 2.3 seconds.

Audi says the E-Tron GT will use a Tesla-like skateboard platform that borrows lots of bits from the Porsche Taycan.

The E-tron GT concept will make its official debut at the Los Angeles Motor Show in November and we’ll be on site for the reveal.

Tesla launches new Model 3 version with Mid-Range battery pack for $45,000

Tesla has announced a new version of Model 3 with a new Mid-Range battery pack and 260 miles of range that will sell for $45,000. That’s $4,000 less than the price of the Long Range battery pack version, which has a 310-mile range.

The rear-wheel-drive option will now only be available with the new Mid-Range pack, and the Long Range pack will only be sold with a dual motor AWD powertrain (Elon Musk says that RWD will still be available with the Long Range pack for a limited time).

Is this a step in the direction of the $35,000 base version that the company has promised?

“As Model 3 production and sales continue to grow rapidly, we’ve achieved a steady volume in manufacturing capacity, allowing us to diversify our product offering to even more customers,” Tesla says. “Our new Mid-Range Battery is being introduced this week in the U.S. and Canada to better meet the varying range needs of the many customers eager to own Model 3, and our delivery estimate for customers who have ordered the Standard Battery is 4-6 months.”

Musk tweeted that the new pack is not a software-limited Long Range pack. “It’s a long range battery with fewer cells. Non-cell portion of the pack is disproportionately high, but we can get it done now instead of ~February.”

There’s Some Secret Tech Lurking In The Tesla Model 3

Specially tuned vertical frequency?

There’s a lot of innovation in the Tesla Model 3. There’s the unique permanent magnet switched reluctance (PMSR) rear motor; the integration of the controls into a single center screen. Even the vents in the car’s HVAC system are a completely new design. Now, we’ve learned more details about other parts of the vehicle that have, quietly, undergone sophisticated development. They’re mostly associated with the chassis and suspension.

These new technical details were discovered by the team at Autocar who spoke to a number of Tesla engineers. They start with the tires, which, we’re told, the automaker spent three years working with tire manufacturers to develop. Besides being filled with sound-dampening foam, the rubber in the tread is formulated to have low-rolling resistance, yet offer good grip for a heavy vehicle with a lower-than-normal center of gravity. They also need to be able to deal with the extreme conditions of spinning at 155 miles per hour. If this sounds obsessive, read on.

The suspension, front and rear, is particularly interesting. The rear suspension, with five separate linkages and a damper, offers the wheels out back “six degrees of freedom,” says Autocar.   We’re told it is similar to a double wishbone setup, but the links have a split, which allows them to offer improved control using the feedback from the tires.

The front suspension, besides doing the typical duty of allowing the front wheels to flex up and down and turn, have an element of crash safety built in. In the case of a front-end collision, “…the front two steering links are designed to break so that the front wheel rotates around the third link, pushing the car away from impact.” Likewise, the mounts for the front motor (on Dual Motor variants, natch) are designed to pivot backward into an empty space in the case of an accident.

Interesting also are the choices made for the braking system. Tesla eschewed a cheaper option and went with four-pot brake calipers, but it didn’t stop there. To keep mechanical friction to a minimum, it engineered the piston seals to “… fully retract the brake pads after braking…” Typically, brake pads are allowed to float a bit, and lightly contact the rotors which keeps them free of surface rust. To accomplish that task, the automaker developed unspecified “new anti-corrosion techniques.

Finally, Autocar wraps up its look at the unseen innovation by informing us about the car’s vertical frequency. Now, this is something probably no one, outside of vehicle dynamics engineers, gives much thought to, but apparently Tesla used NASA data to target the frequency that would keep drivers feeling comfortable. While not saying what value it targeted —it does say autos typically range from 1.0 to 3.0 Hertz — the Model 3 is tuned to have a vertical frequency  “…equivalent of a brisk walk or a slow run,” that helps the car keep a sporty feel, but still keep occupants comfortable. Neat-o!

Germany Launches Funded Institution For Solid-State Battery Development

FestBatt to accelerate solid-state battery development.

Germany’s Ministry of Education and Research (BMBF) intends to support development of solid-state batteries in the country, quite similar to the example in Japan earlier this year, by launching FestBatt competence cluster.

FestBatt, coordinated by the University of Gießen (JLU), received €16 million ($18.3 million) for operations and already gathered 14 fourteen scientific institutions, which will work on five joint projects: three materials and two methods platforms.

According to the press release, solid-state batteries are seen as very promising, but still require a lot of research and most projects are the basic ones because there are huge material obstacles before even prototype cells can be made.

Our first thought on the initiative is that German institutions are far behind some individual companies around the world, because otherwise, no research center would join a bigger group if an in-house advanced prototype already existed.
