We’ve long known that inside of Rivian, the popular electric pickup and SUV maker, lived a tiny skunkworks of e-bike folks ready to reinvent the micromobility world with their own take on the future of rideables. After the company was spun off and brought to public attention last year, we finally know what they’ve been cooking up today. And it might just be the future of the electric bike.
Before we start, it must be said that Micah’s sleuthing and connections did bring us two pretty amazing sneak previews of what we are seeing today. But I think these views only tell a very small part of the story.
It is an e-bike, but unlike any e-bike we’ve ever seen
ALSO’s TM-B is its ebike platform. I say platform because the bike is extraordinarily modular….and there’s a big ‘one more thing’ here.
The first feature that we were shown was its ability to go from a traditional bike seat to a bench seat to a cargo bike seat in seconds with a quick settings change on the front control module. Each seat can be tied to a profile, so for instance, a family could own a bike and each member has their own seat selection, and their profile would go along with the seat. You can, of course, have just 1 seat and many profiles connected to that seat, and vice versa, with your one profile connected to multiple seats.
Other less fancy modularities include the wheels, fenders, colorways and other items that change the complexion of the bike quite dramatically. So that means that this bike can check the cargo bike, street commuter bike, and off-road bike checkboxes. The look? It is admittedly polarizing but also playful and I think will strike the broad swath of the population in a positive way.
The tire size is 24 inches, and the company uses off-the-shelf tires here, unlike most of the bespoke bike. There is an off-road setup and a commuter road setup, and of course, users can go out and buy and ride on any standard 24-inch set of tires.
The TM-B has full suspension that is quite soft with 12mm of travel on front and back. I asked about a suspension bike seat, but after riding, I don’t think it is necessary. What the big 24-inch tires didn’t absorb, the adjustable suspension did wonders.
Square at the center of the bike
It is hard to ignore the block at the center of the TM-B ebike. This houses the battery, much of the smarts, the motors, and the pedal-by-wire generator.
Battery:
Finally. An e-bike company has embraced USB-C in a big way. Micah and I have been arguing about this for years and it seems like a head-scratcher that no ebike company has embraced this, until now.
The bike charges on a 240W USB-C cable. While that’s not the fastest charging available, I believe that the benefits far outweigh the cons. For instance, you can charge this bike with just about any USB-C charger. Grab that MacBook cable at work. Use that phone charger at your parents’ house. While this won’t quick-charge the TM-B in an hour, it allows it to charge just about anywhere.
The included 240W Power brick will charge the 800Wh battery in just over 3 hours from dead. Not bad.
The battery is also removable and can discharge via USB-C, too, so you have a built-in 800Wh Jackery-type battery to take with you. Or if you live in an apartment, it is easy to take the battery up your steps to charge. This is clearly where the industry is headed. I asked ALSO if they would be doing a 120V AC inverter product and they deferred to a possible 3rd party market of USB-C to AC adapters. These will obviously top out at 240W so don’t expect to use Rivian’s Camp Kitchen here.
But the possibilities don’t stop there. For instance, you could add extra range to this bike with those huge, cheap USB-C batteries. It goes without saying that you can also charge things from your bike as you ride. Most notably your phone in a very quick way though ALSO doesn’t include one of those claw phone holders. The company believes you will use the NEST-like interface to do all of your phone-type stuff. That remains to be seen.
I suggested that ALSO should turn this into a battery-charging Peloton-type stationary bike and the engineers looked at each other and said they could knock this out in a matter of days if they thought the industry wanted this. One of the many benefits of owning the full stack of software on this ebike. I think an excercise to charge the bike and a bunch of other stuff would be a fun little trick so make sure you tell the company if you want something like this.
Pedal-by-wire
Micah and I have also talked about how the advantages of pedal-by-wire on ebikes outweigh the cons –specifically the efficiency loss in conversion from physical energy to electrical and back. ALSO says these losses are minimal and aren’t material to the experience.
Plus, it enables not only a smoother pedalling experience, but it also allows you to pedal at your desired cadence and torque, which allows the rider to optimize the output wattage. The computer controls exactly how much electricity is generated from your pedalling (and regenerated from braking) and how much to send via Gates belt drive to the rear wheel.
In the default mode, the pedalling controls the speed in a way that is intuitive for bike users, so that the harder you pedal, the faster you go. There is an off-road mode that simulates gear shifting, which is a trip since it feels so real, even though my mind knows it is a simulation.
Sur Ron acceleration
One of the most striking things about this bike is the acceleration that is output from this realtively small battery and motor. I’ve ridden on a ton of Sur Rons and Talarias and the acceleration to 20mph is ALMOST comparable, even up significant hils. It is really incredible and speaks to the efficiency of the bespoke battery and the motor.
Why is this important? Well, will also tell you, and I agree, that it is important to beat cars off the line so that riders don’t get side-swiped as easily.
But also kids love that acceleration but parents want safe rides. This hits that Sur Ron type of fun acceleration without having top speeds in the 40-60mph range. The ALSO TM-B is a Class 2-3 ebike, which means you can throttle to 20mph and pedal assist to 28mph. As a 200lb fast ebike enthusiast, I was blown away by the almost immediate 0-20mph acceleration at the highest of the 10 assist and throttle levels. ALSO will respect and adjust the TM-B to have other country-specific outputs like 500W for Canada and 250W for the EU.
That said, ASLO prefers to list its power in torque and prefers to measure that way. I’m not sure if that’s to skirt laws on output, but I’m in favor of whatever gives me car-beating power. It lists 180nm of torque and up to 10x “assist multiplier,” which is bananas if you consider that I regularly put out 250W of power. As for hills, it lists 30% which should tackle the worst hills around, including San Francisco, which is shown prominently in ALSO’s marketing.
The ALSO TM-B experience
I got on a bike that was off, and the pedals felt like the chain had disconnected on a regular bike. No resistance, just spin. This is how the bike will act if it is stolen. The rear wheel will also lock out, and the electronics will be unusable outside of tracking the location of the bike. This makes the TM-B almost pointless to steal, a huge boon for people who’ve been burned by bike theft in the past.
But once you turn on the bike and click in, it feels a lot like a belt-driven e-bike. The connection to the drivetrain is virtual. After all, you are just generating electricity by pedalling. But the ALSO engineers have done an excellent job of creating a virtual experience that makes it feel like you are pedalling a bike. Remember that you don’t need gears in a pedal-by-wire scenario so it doesn’t require too much clicking over. You do feel some movement as the generator switches the amount of power you are generating.
The power, like I’ve said a few times before, is pretty incredible. But the bike is also incredibly stable, especially for something with so much technology built in.
