SINET™ is the current E-BikeKit electrical platform used across our current-generation conversion systems. It combines matched controls, display, pedal-assist inputs, throttle, brake cutoffs, motor connection, and battery/controller architecture into one coordinated system.

Current battery-included SINET™ systems use a 48V platform with a 3.5" full-color LCD, matched waterproof connectors, throttle-on-demand, e-brake motor cutoffs, and either cadence or torque-sensing pedal assist where offered.

Do not assume they are interchangeable. SINET™ and Legacy E-BikeKit/E-TrikeKit components should be treated as separate component families unless a product page specifically states compatibility.

Connectors, controllers, displays, throttles, brake inputs, pedal-assist components, and battery interfaces have changed across product generations. If you are repairing an older system, identify whether you have a SINET™ or Legacy system before ordering replacement parts.

If you are unsure, contact us with photos of your display, controller, connectors, battery, and motor cable before ordering.

Compatibility depends on the specific conversion system and the bike or trike being converted. Important factors can include wheel size, front or rear dropout type and spacing, axle style, drivetrain configuration, brake setup, bottom bracket configuration, and battery mounting space.

Many current systems require conventional slotted dropouts. Thru-axle frames or forks are not compatible with systems designed around a conventional bolt-on hub-motor axle.

For model-specific systems, use the compatibility information on that product page. If you are unsure, contact us before ordering and send clear photos of the bike or trike and the areas involved in the conversion.

The correct choice depends on the bike or trike. A front-wheel conversion can leave the rear drivetrain unchanged and is used on many of our model-specific trike systems. Rear-wheel systems may be preferred or required for other applications.

Do not choose only by preference. Dropout spacing, axle type, brakes, drivetrain, wheel size, frame design, and the intended application all matter. Use the configuration information on the product page or contact us if you need help choosing.

A model-specific system is configured around a particular bike or trike platform instead of requiring the customer to assemble a generic combination of parts. Depending on the model, this can include a specific motor-wheel size, battery mounting hardware, cable requirements, display mounting hardware, drivetrain configuration, and installation components.

Always read the individual model-specific product page because included hardware and compatibility requirements differ by model.

Cadence sensing detects that the cranks are rotating and provides assistance according to the pedal-assist level selected on the display. It is generally the simpler installation.

Torque sensing measures how hard the rider is pedaling and varies motor assistance in proportion to rider effort. This usually creates a more natural, bicycle-like feel.

Torque-sensor installation is more involved and requires compatible bottom-bracket fitment. Review the product page and installation information for the system you are considering.

The standard SINET™ bottom bracket torque sensor used on current E-BikeKit systems is designed around a compatible 68 mm square-taper bottom bracket.

Installation requires removal of the existing crank arms and bottom bracket. Current installations also require protected routing for the torque-sensor cable through the bottom bracket shell as described in the applicable product and installation instructions.

Some traditional upright trikes use a one-piece crank and require additional crank-conversion components. If a product requires those parts, the product page will identify them.

Yes. Current SINET™ conversion systems include throttle-on-demand in addition to the selected pedal-assist system unless a product page specifically states otherwise.

The throttle can be used independently of pedal assist, while cadence or torque sensing provides assistance when pedaling.

Top speed depends on the specific system, wheel size, programming, rider and cargo weight, terrain, tire size, battery condition, and other operating conditions.

Because E-BikeKit offers several bike- and trike-specific configurations, there is no single speed specification that applies to every conversion. Use the performance specifications on the individual product page for the system you are considering.

Range varies substantially with battery capacity, rider and cargo weight, terrain, speed, tire pressure, temperature, throttle use, pedal input, and pedal-assist level.

Current battery-included model-specific systems commonly use our 48V 15Ah battery. Refer to the individual product page for the range estimate assigned to that particular system rather than treating one range figure as universal.

Yes, electric assist can substantially reduce the effort required on hills, but climbing ability depends on grade, total load, speed, traction, system configuration, and rider input.

On steep grades or with heavier loads, pedal input is important. A conversion system should be used as an assist system rather than assuming every hill can be climbed on throttle alone.

Order the wheel size required by the bike, trike, or model-specific system shown on the product page. Some model-specific products have a fixed wheel size; others allow you to choose from supported sizes.

Unless the product page specifically states otherwise, motor wheels are supplied with the specified rim/build components and the tire and tube are not included. Review the individual product listing before ordering.

E-BikeKit conversion systems are supplied with a motor wheel built for the application. Our motor wheels are professionally built around the hub motor using the rim and spoke specification selected for the system.

If you have a special wheel requirement, contact us before ordering rather than assuming an existing rim can be reused.

A hub motor applies torque through its axle into the bicycle or tricycle dropouts. Torque arms provide additional axle retention and help transfer that load safely into the fork or frame.

Use the torque-arm configuration supplied or specified for your conversion system. Some model-specific applications require more than one torque arm. Follow the instructions for the product you are installing.

Many mechanically experienced customers install their own conversion systems. Installation can involve wheel removal and installation, axle hardware and torque arms, brake controls, battery mounting, wiring, display and throttle installation, and pedal-assist installation.

Bottom bracket torque sensing requires additional bottom-bracket work and cable routing. If you are not comfortable with the required bicycle and electrical work, professional bicycle-shop or E-BikeKit dealer installation is recommended.

Current battery-included SINET™ systems use the battery specified on the individual product page. Many current model-specific systems include the E-BikeKit 48V 15Ah lithium-ion battery, matching 3A charger, and SINET™ battery/controller cradle.

Battery mounting hardware varies by product. Model-specific systems may include a dedicated mounting solution, while other systems may require a suitable mounting location or separately specified hardware.

Some E-BikeKit systems are offered without a battery specifically for customers who already have an appropriate battery. Current no-battery SINET™ systems require a compatible 48V battery and the correct electrical connection.

Voltage alone does not establish compatibility. Connector type, polarity, discharge capability, battery condition, battery-management system, mounting, and the requirements of the specific controller must also be appropriate.

If you are unsure, contact us before connecting a third-party battery. Photos of the battery label, connector, and mounting arrangement are helpful.

With the current 3A charger, a substantially discharged 48V 15Ah battery typically requires approximately 5 hours to recharge. A partially discharged battery will generally require less time.

Use the charger specified for the battery and follow the battery and charger instructions.

Keep the battery dry, protect it from physical damage and extreme temperatures, and use the correct charger. Do not leave a lithium battery completely discharged for an extended period.

For longer storage, keep the battery in a cool, dry indoor location and periodically check its state of charge. Inspect the battery, cradle, wiring, and connectors before use if the system has been stored for an extended period.

Current SINET™ systems use matched weather-resistant electrical connectors and are designed for normal outdoor riding conditions, including getting caught in rain.

The system should not be submerged or pressure-washed. Protect the bike or trike from prolonged exposure when parked, and keep the battery and electrical components dry and properly maintained whenever possible.

No. Current E-BikeKit SINET™ conversion systems do not use regenerative braking to recharge the battery while riding. The battery is recharged with the specified external charger.

E-BikeKit conversion systems are assembled in Pennsylvania, USA, and our hub-motor wheels are hand-built in the USA. Electrical components, batteries, hub motors, and other components are sourced from specialized manufacturing partners, including overseas suppliers.

Small parts typically ship the same business day when ordered before noon ET. Larger kits, wheels, and battery shipments usually ship within 1–2 business days unless otherwise noted on the product page or during periods of unusually high order volume.

Lithium-ion batteries ship separately via FedEx Hazmat and may require a delivery signature. It is normal for a conversion system, battery, charger, or mounting hardware to arrive in separate packages or on different days.

International availability depends on the product and destination. Lithium batteries are subject to significant transportation restrictions and may not be available for international shipment.

Contact E-BikeKit before placing an international order if the order includes a battery or if you need help confirming available shipping options for your destination. Import duties, taxes, brokerage fees, and other destination-country charges are the responsibility of the buyer unless otherwise stated.

Start with the individual product page because it contains the most specific compatibility, configuration, installation, and included-component information for that system.

If you still need help, call E-BikeKit toll-free at 1-866-882-3245, Monday–Friday, 9am–5pm ET, or email support@ebikekit.com.

For compatibility questions, photos are extremely helpful. Send clear photos of the bike or trike, dropouts/fork, drivetrain, bottom bracket/crank area, battery label, and connectors as applicable.
