These ‘digital drive’ bikes replace a bicycle chain with software
Ever heard of a “digital drive” bike? It might seem like a strange concept, but several companies are developing commercial offerings that use electronics instead of a bike chain to power a bicycle’s rear wheel.
A digital drive is essentially a form of series hybrid electric bike, unlike a conventional e-bike that is more of a parallel hybrid. On many conventional e-bikes, the rider can either power the bike completely manually with the pedals or completely electronically with the throttle. But in a series hybrid e-bike, which is another term for digital drive, the rider powers the pedals manually that then feed directly into a generator to power the motor in the rear wheel electronically, no chain needed.
The chainring (the big gear by the pedals) is replaced by a generator, and the chain is replaced by software that helps mimic the feeling of a bicycle chain by providing similar resistance.
But without any mechanical power delivery, there’s no chain to rust or gears to adjust. That removes nearly all maintenance associated with a bike’s drivetrain, leaving just the tires and brake pads as the only regular maintenance items.
It also provides a simple form of automatic shifting, though in practice it would be more like an infinitely variable gear range. Software control regulates the pedal resistance, meaning that any gear ratio could be achieved from the same pedal cadence. Riders could even program in their optimal customized pedal cadence based on their own comfort. The problem of getting bogged down on an uphill climb or running out of gears on a downhill would cease to exist.
Gearbox/motor drivetrains exist, but they’re pricey and complex. A digital drive setup like this would be a simpler way to achieve a similar effect.
Digital drivetrains typically still use an e-bike battery as a buffer, allowing for some stored energy to compensate for lower rider input, or storing extra energy when the rider is pedaling hard enough to generate more power than is needed for propulsion. But a lighter and more powerful super-capacitor could also be used in lieu of a battery, shaving many pounds off the weight of a typical e-bike battery.
Companies like Schaeffler have shown off ride-by-wire electric bike drivetrains that use this type of series hybrid approach, though with conventional electric bike batteries.
The Danish company Bike2 is another drive maker that has spent years developing its own digital drive setup, though the technology was taken over this year by the Dutch company Alligt.
Electrek’s Take
The idea of digital drive for e-bikes in interesting and not without several advantages, but it also adds in some unnecessary complication, in my opinion.
For a simple commuter bike, I can understand the argument that the added complexity isn’t worth it. However, I can also see cases where digital drive could be a major advantage.
For cargo bikes, especially larger cargo bikes that have long chain runs, digital drive can clean up the drivetrain and allow designers more freedom in the bike’s geometry. Think of those e-bikes with giant cargo boxes on the rear. There’s usually a long tunnel down the middle at the bottom of the box to allow for the chain to pass through, or the box has to start up much higher. But the lack of a chain could mean the box is mounted much lower, resulting in more cargo space and a lower center of gravity, improving the stability of the bike.
In talking about it with Electrek’s publisher Seth Weintraub, he pointed out that recumbent bikes could also stand to benefit. Many have incredibly long chain runs with long plastic tubes for routing chains around the frame. Digital drive would simplify those complex drivetrains while allowing for an even more stretched geometry.
So while the technology might be a bit overhyped, there appear to be real uses cases that could stand to benefit from digital drive.

Is it an electric van or a truck? The Kia PV5 might be in a class of its own. Kia’s electric van was recently spotted charging in public with an open bed, and it looks like a real truck.
Kia’s electric van morphs into a truck with an open bed
The PV5 is the first of a series of electric vans as part of Kia’s new Platform Beyond Vehicle business (PBV). Kia claims the PBVs are more than vans, they are “total mobility solutions,” equipped with Hyundai’s advanced software.
Based on the flexible new EV platform, E-GMP.S, Kia has several new variants in the pipeline, including camper vans, refrigerated trucks, luxury “Prime” models for passenger use, and an open bed model.
Kia launched the PV5 Passenger and Cargo in the UK earlier this year for business and personal use. We knew more were coming, but now we are getting a look at a new variant in public.
Although we got a brief glimpse of it earlier this month driving by in Korea, Kia’s electric van was spotted charging in public with an open bed.
The folks at HealerTV found the PV5 variant with an open bed parked in Korea, offering us a good look from all angles.
From the front, it resembles the Passenger and Cargo variants, featuring slim vertical LED headlights. However, from the side, it’s an entirely different vehicle. The truck sits low to the ground, similar to the one captured driving earlier this month.
When you look at it from the back, you can’t even tell it’s the PV5. It looks like any other cargo truck with an open bed.
The PV5 open bed measures 5,000 mm in length, 1,900 mm in width, and 2,000 mm in height, with a wheelbase of 3,000 mm. Although Kia has yet to say how big the bed will be, the reporter mentions it doesn’t look that deep, but it’s wide enough to carry a good load.
The open bed will be one of several PV5 variants that Kia plans to launch in Europe and Korea later this year, alongside the Passenger, Cargo, and Chassis Cab configurations.
In Europe, the PV5 Passenger is available with two battery pack options: 51.5 kWh or 71.2 kWh, providing WLTP ranges of 179 miles and 249 miles, respectively. The Cargo variant is rated with a WLTP range of 181 miles or 247 miles.
Kia will reveal battery specs closer to launch for the open bed variant, but claims it “has the longest driving range among compact commercial EVs in its class.”
In 2027, Kia will launch the larger PV7, followed by an even bigger PV9 in 2029. There’s also a smaller PV1 in the works, which is expected to arrive sometime next year or in 2027.
What do you think of Kia’s electric van? Will it be a game changer? With plenty of variants on the way, it has a good chance. Let us know your thoughts in the comments below.

Is Nissan raising the red flag? Nissan is cutting about 15% of its workforce and is now asking suppliers for more time to make payments.
Nissan starts job cuts, asks supplier to delay payments
As part of its recovery plan, Nissan announced in May that it plans to cut 20,000 jobs, or around 15% of its global workforce. It’s also closing several factories to free up cash and reduce costs.
Nissan said it will begin talks with employees at its Sunderland plant in the UK this week about voluntary retirement opportunities. The company is aiming to lay off around 250 workers.
The Sunderland plant is the largest employer in the city with around 6,000 workers and is critical piece to Nissan’s comeback. Nissan will build its next-gen electric vehicles at the facility, including the new LEAF, Juke, and Qashqai.
According to several emails and company documents (via Reuters), Nissan is also working with its suppliers to for more time to make payments.
“They could choose to be paid immediately or opt for a later payment,” Nissan said. The company explained in a statement to Reuters that it had incentivized some of its suppliers in Europe and the UK to accept more flexible payment terms, at no extra cost.
The emails show that the move would free up cash for the first quarter (April to June), similar to its request before the end of the financial year.
One employee said in an email to co-workers that Nissan was asking suppliers “again” to delay payments. The emails, viewed by Reuters, were exchanged between Nissan workers in Europe and the United Kingdom.
Nissan is taking immediate action as part of its recovery plan, aiming to turn things around, the company said in a statement.
“While we are taking these actions, we aim for sufficient liquidity to weather the costs of the turnaround actions and redeem bond maturities,” the company said.
Nissan didn’t comment on the internal discussions, but the emails did reveal it gave suppliers two options. They could either delay payments at a higher interest rate, or HSBC would make the payment, and Nissan would repay the bank with interest.
The company had 2.2 trillion yen ($15.2 billion) in cash and equivalents at the end of March, but it has around 700 billion yen ($4.9 billion) in debt that’s due later this year.
As part of Re:Nissan, the Japanese automaker’s recovery plan, Nissan looks to cut costs by 250 billion yen. By fiscal year 2026, it plans to return to profitability.
Electrek’s Take
With an aging vehicle lineup and a wave of new low-cost rivals from China, like BYD, Nissan is quickly falling behind.
Nissan is launching several new electric and hybrid vehicles over the next few years, including the next-gen LEAF, which is expected to help boost sales.
In China, the world’s largest EV market, Nissan’s first dedicated electric sedan, the N7, is off to a hot start with over 20,000 orders in 50 days.
The N7 will play a role in Nissan’s recovery efforts as it plans to export it to overseas markets. It will be one of nine new energy vehicles, including EVs and PHEVs, that Nissan plans to launch in China.
Can Nissan turn things around? Or will it continue falling behind the pack? Let us know your thoughts in the comments below.
