This hub is written for importers, distributors and DTC brand owners planning a private-label commuter program. The EMT-B001 platform sits at the centre of most of those programs: a 27.5-inch aluminium Sea Dragon frame, a 48V 350W drive, Shimano 21-speed gearing and a 200 kg load design. Buyers specifying an urban electric mountain bike for dense city traffic, and buyers specifying a 48V 350W electric mountain bike for hillier commuter routes, are configuring the same base platform against two different briefs — which is exactly what this page helps you plan.
Platform snapshot
Every figure below is published on the EMT-B001 product page. The status column tells you whether an item is fixed on the platform or can be varied for your own program.
| Specification | Published value | Status |
|---|---|---|
| Frame | 27.5″ aluminium Sea Dragon mountain bike frame | Fixed |
| Motor power | 48V 350W | Fixed |
| Battery | Li 36V/10.4Ah | Configurable |
| Max speed | 45 km/h | Configurable |
| Max range | 80–90 km | Configurable |
| Max loading | 200 kg | Fixed |
| Gear | Shimano 21 speed | Fixed |
| Display | LCD digital display | Configurable |
| Tyre / wheel size | Outer tyre 27.5×2.6 inches | Fixed |
| Charging time | 6–8 hours | Fixed |
| Packaging size | 1460×220×710 mm | Configurable |
Confirm final configuration with our team. The figures above are the platform record; the battery, speed setting, display, range result and packaging are agreed at spec lock so that one authoritative version travels with your order.
Customization matrix
This is the split your first email should ask about. Left is the platform you inherit; right is what your program can change before sampling begins.
These are the parts of the EMT-B001 that every buyer receives, so tooling, testing and documentation carry over between programs.
Only raise an item here if the factory can genuinely vary it for your volume — that is the first thing a sourcing team will test in reply.
End-market fit
Read these as segmentation input for your own catalogue planning, not as marketing copy. Each rider group implies a different configuration brief and a different retail price band.
Positioned as an alternative to traffic jams and crowded subways, with electric assistance across a long daily commute and no sweat-stained clothing on arrival.
A lightweight body that can be lifted and carried, with enough power for a full day of commuting between classes.
Built for short-distance cycling trips and light off-road adventure, with climbing assistance and single-day range coverage.
Stable power output suited to park and greenway rides, where predictable assist matters more than peak performance.
OEM/ODM process
Greennovo runs OEM and ODM programs on this platform. The sequence below is the path your order follows; the timing of each stage is confirmed at spec lock, because no two configurations share the same schedule.
Share your target market, expected volume and configuration intent so the platform is discussed against your brief.
Agree fixed versus selectable items: battery, display, gearing, speed setting, branding and packaging.
A pre-production unit is built to the locked specification for your evaluation.
Ride test, fit check and packaging review, followed by written approval of the sample.
Volume, delivery schedule and shipping terms are confirmed against the approved configuration.
Production runs against the approved sample so the specification does not drift between units.
Inspection of the batch plus the paperwork pack prepared for the shipment.
Master carton pack-out, container loading and dispatch to your destination.
Unit economics
No prices are published for this platform, because cost is configuration-driven and quote-based. The table shows which decisions move cost and in which direction.
| Decision variable | What changes | Directional cost effect | What to decide |
|---|---|---|---|
| Battery capacity and voltage | Watt-hour capacity in the pack | Higher capacity generally adds unit cost | Size the pack to your buyers’ real commuting distance, not to the maximum range figure |
| Drive class | Output class of the motor | Higher-output classes generally add unit cost | Keep the 48V 350W class unless your terrain or market genuinely demands more |
| Display unit | Feature set of the on-board display | Added features generally add unit cost | Match the display to what your customer actually uses daily |
| Gearing specification | Beyond the Shimano 21-speed baseline | Spec changes move unit cost in either direction | Keep the baseline unless your routes demand different ratios |
| Branding and decal package | Artwork, decals and retail printing | More custom artwork adds unit cost | Lock branding early so artwork is not reworked after sampling |
| Order quantity | Units per order and per container | Unit cost generally improves with volume | Align the container plan with your sell-through rate rather than stock-holding capacity |
| Packaging and master carton | Carton specification and pack-out | Heavier or more protective cartons add cost | Balance damage protection against freight weight |
Cost direction is shown qualitatively because unit cost depends on your locked configuration and order volume. Request a quote for numbers against your brief.
Documentation and compliance
Ask for these during the inquiry stage so they are built into your program rather than added afterwards. All items below are available on request — no certification is claimed on this page.
Request the current test documentation for the EMT-B001 platform and state which market the paperwork is intended for.
Documentation follows the pack you configure, so the battery decision and the paperwork request should be made together.
Packing documentation for the 1460×220×710 mm platform carton, adjusted for your selected master carton format.
The platform table lists a 45 km/h maximum speed. Where your market caps electric assistance at a lower figure, request the speed setting at spec lock.
Scenario to specification
Use this table to turn a market segment into a configuration brief before you contact the team. Every row maps a real riding scenario to platform facts and the decision that follows from it.
| Riding scenario | Spec emphasis | Buyer decision |
|---|---|---|
| Stop-start city traffic | 27.5-inch aluminium frame, LCD display, 6–8 hour charging | Plan battery capacity and the buyer’s charging routine around real commute length |
| Campus and all-day commuting | Lightweight liftable aluminium frame with all-day assistance | Choose paint and branding for a younger retail line and confirm the market speed setting |
| Hillier commuter routes | 48V 350W drive class with Shimano 21-speed gearing | Lock gearing and tyre specification before the sample is built |
| Park and greenway riding | Stable power output, 45 km/h published maximum speed, LCD display | Specify a simpler display and a single paint for a value-led line |
| Multi-model retail catalogue | Fixed platform with selectable battery, display, gearing and packaging | Build two SKUs from one platform to reduce tooling and documentation risk |
Request for quotation
Send your target market, expected order quantity and the configuration items you want to vary from the fixed platform. You will receive a quotation and the documentation pack that matches your configuration, including any market-specific speed setting.
Requests for samples, private-label branding, bulk orders and packaging customization are all handled through the same quotation process.

it is quote-driven. there is no price, cart or checkout on the product page. greennovo operates oem and odm services, so the platform is quoted against your configuration, branding and order volume.
the platform table lists a 45 km/h maximum speed. where your destination market caps electric assistance at a lower figure, request the speed setting during spec lock so it is applied before production.
test reports for the platform, battery documentation for the pack you configure, and packing documentation for the master carton are available on request. no certification is claimed on this page, so ask the team which paperwork applies to your destination market.
