Mid-Drive Motor Architecture
Our DriveCore M2 places the motor at the bottom bracket for true center-of-gravity handling. 750W nominal, 1,200W peak, with a torque sensor sampling pedal input 1,000 times per second.
Customem Engineering
Drivetrain, Battery & Build Engineering
Three proprietary systems — our mid-drive motor architecture, modular battery platform, and concierge custom-build process — engineered in California and refined across 14 production iterations to deliver the most coherent electric bike on the road.

Over-the-air firmware, anti-theat geofence, ride telemetry and Class 1/2/3 mode switching from the bar.
Engineering Pillars
Six disciplines, one coherent machine.
Every Customem bike is the product of six engineering disciplines working in concert — not a parts bin assembled by a contract manufacturer. Below is what each team owns, end to end.
Modular Battery Platform
CellStack uses 21700-format Samsung/LG cells in a CNC-housed pack with active balancing. Range from 40 to 110 miles depending on configuration, hot-swappable in under 8 seconds.
Forged Frame Engineering
Every frame begins as a hydroformed 6061-T6 tube set, robot-welded in jigs to ±0.2 mm tolerance. Internal cable routing, integrated battery slot, and a lifetime warranty against fatigue.
Customem OS & Telemetry
Our firmware ships with every bike. Bluetooth 5.2 pairing, OTA updates, ride history export, theft-deterrent geofencing, and a USB-C service port for dealer diagnostics.
Concierge Custom Build
Choose your frame size, color, battery capacity, drivetrain, and accessory loadout in our online configurator. Each bike is hand-finished and tuned at our Oakland facility.
Service & Lifetime Support
Every Customem includes 3 years of comprehensive coverage and lifetime drivetrain support. 180+ authorized service partners nationwide, plus mail-in repair and a 30-day ride-it guarantee.
The Build Process
From your spec sheet to your doorstep.
No mystery, no middlemen. Every Customem follows the same four-stage journey from digital configurator to first ride — and you can track it the whole way.

02
Hand-Assembled
Your bike enters our Oakland build queue. One technician owns it from bare frame to torque-checked final.
03
QA Tuned
30-point inspection, firmware flash, brake bed-in, and a 2-mile test ride logged before crating.
04
White-Glove Delivery
Freight-crated, fully insured, and scheduled to your door. In-person setup available in 12 metros.
Why Customem
Numbers we’re proud of.
Engineering credibility is built in test data, not marketing copy. Here are the figures that put our drivetrain and battery platform at the top of the category.
1,200
Charge cycles to 80% capacity
CellStack packs are conservatively rated. Independent lab testing at 1C discharge and 0.5C charge shows 82% retained capacity after 1,200 full cycles — roughly 7 years of daily commuting.
99.4%
First-30-day reliability score
Across 18,400 bikes shipped in 2024, fewer than 0.6% reported any issue in the first 30 days of ownership — well below the category average of 4.1%.
8 yrs
Frame fatigue warranty
We warrant the main frame and DriveCore motor housing against manufacturing defects for eight years. The drivetrain, electronics, and battery carry three years of comprehensive coverage.
Rider Testimony
What owners say after 5,000 miles.
A long-term review from two Customem owners who put their bikes through the kind of daily, weather-beaten use the marketing team would never recommend.
After 11,000 miles on my Customem Commuter Pro, the only thing I’ve replaced is a set of brake pads and a chain at 8,000 miles. The DriveCore motor is quieter than my refrigerator and the battery still shows 96% of original capacity — verified at my local shop on their Cycle Analyst.
I ordered a custom build for delivery in Truckee — steep grades, sub-zero winters, forest-service fire roads. The team walked me through the configurator for forty minutes, spec’d a higher-capacity pack and the knobby tire package, and the bike has been flawless. Best purchase I’ve made in a decade.
