The installation sounds straightforward, but “any bike” is not established: wheel, axle and brake compatibility need checking before purchase.
How the Unlimited conversion kit works
New Atlas reported on July 13, 2020, that the basic kit included a hub-motor front wheel offered in a range of sizes, a battery pack, a quick-release battery plate and a wireless pedal sensor. The plate attaches to the bicycle’s bottle-cage mounting holes; the sensor straps to the crank arm. The motor assists through the front wheel when the system detects pedaling.
Reported installation steps
- Remove the bicycle’s existing front wheel and install the supplied motor wheel.
- If the bicycle has a disc brake, transfer its rotor to the replacement wheel.
- Attach the battery mounting plate to the bottle-cage holes, then position and connect the battery.
- Route the wire along the front fork.
- Secure the wireless pedal sensor to the crank arm.
These steps reflect New Atlas’s 2020 description, not an independent hands-on installation test. The article says the sensor uses accelerometers and other sensors to detect pedaling and direction.
Will it fit your bicycle?
Not necessarily. New Atlas said the front wheel was offered in a range of sizes and called the setup broadly compatible, but did not publish a complete compatibility chart. Its report does not establish compatible axle standards, brake clearances, every wheel size or frame constraints. A disc-brake bicycle also needs a compatible rotor transfer to the replacement wheel.

Before buying any particular kit, verify its current fit information against your bicycle’s wheel diameter, axle type, brake system and available bottle-cage mounts. The article also described a rear-motor version, but said it was harder to fit and did not work with every wheel type.
What performance and controls did the 2020 report describe?
New Atlas reported two configurations: 250 W with a stated top speed of 25 km/h, described in the article as “Euro-legal,” and 750 W with a stated top speed of 22 mph, described as “US-legal.” Those are the report’s 2020 descriptions, not current legal guidance; applicable e-bike rules depend on location and configuration.

The article gave assisted-range claims of 35 km (22 mi) for the smaller battery and 80 km (50 mi) for the larger battery. These are product figures reported by New Atlas, not independently tested results; the article does not state test conditions. It also mentioned app control, an optional wired display and a thumb throttle.
Price and availability are historical, not current
New Atlas reported a €449 (US$510) starting early-bird price through Indiegogo in 2020, with delivery then slated to begin in November 2020 “if all goes to plan.” That launch report does not establish that the kit is currently sold, supported or available at that price. Check a current listing and the manufacturer’s present compatibility information before making a purchase decision.

What to compare before choosing a conversion kit
- Motor position: Front-wheel installation can avoid replacing the rear wheel, while the reported rear-motor variant was more difficult to fit.
- Wheel and axle fit: Confirm the exact wheel size and axle interface rather than relying on a broad “fits most” claim.
- Brakes: Check rotor compatibility and clearance for a disc-brake setup.
- Battery and range: Compare battery capacity and look for range results from a clearly described, independent test; the figures in the 2020 report are product claims.
- Installation and controls: Check what wiring and mounting work is required and whether app, display or throttle controls are included or optional.
- Local rules: Confirm the motor’s power, assistance speed and controls comply with the rules where you ride.
