XIKOBY MX500 36V Controller & Twist-Throttle Kit for Razor MX650/MX500/SX500 — 6‑Pin, 3 Power Modes

High-performance 36V replacement controller and twist-throttle kit for Razor MX500/MX650/SX500 electric dirt bikes and compatible scooters.

This XIKOBY MX500 Controller and Throttle Kit is a direct-fit electronic module and grip-style throttle made to restore or upgrade the speed and throttle response of multiple Razor models and similar 36V electric bikes and scooters. It combines a compact control board, integrated safety cutoffs, and a rubber twist grip that fits standard twist-throttle handlebars. The kit is intended for repair or replacement when the original controller or throttle becomes unreliable or damaged.

Will this controller work with my Razor MX650, MX500, or SX500?

Compatibility is broad but not universal. The controller is designed for 36V systems and lists specific Razor models plus several scooters and ATVs; confirm connector type and physical fit before ordering.

• Compatible models: Razor MX500 (V21+), MX650 (V14+), SX500, McGrath dirt rocket.
• Also compatible with Pocket Mod Bellezza scooters, EcoSmart Metro, RSF650, and many 500cc-style dirt quads.
• Throttle connector: 6-pin male — verify your vehicle uses the same plug.
• Check mounting dimensions and wiring layout to ensure direct replacement.

How does the controller protect my battery and motor?

The XIKOBY module uses constant-current control logic and built-in overload safeguards to help stabilize current draw and disengage the motor if pack voltage drops too low. These behaviors reduce stress on the battery and cut the motor output in unsafe conditions.

• Constant current control smooths acceleration and limits sudden current spikes.
• Automatic motor shutoff triggers when battery voltage falls below a set threshold.
• Using U.S.-standard wiring: 14AWG motor power, 20AWG control cable for reliable connections.
• Overload protection helps prevent thermal or electrical damage during stalls or short conditions.

What features does the throttle and grip offer?

The included twist-grip throttle provides three selectable power modes and an anti-slip rubber surface for better hand control. It’s made to match bikes that originally used a twist-throttle interface and is built for durability and comfortable handling.

• Three power modes: full, low, and a standard power setting for adaptable ride feel.
• Textured rubber grip improves hold in wet or muddy conditions.
• Durable construction intended for frequent use on off-road bikes and scooters.
• Simple plug-and-play throttle connection if your vehicle uses the 6-pin connector noted.

What technical details should I confirm before purchasing?

Confirm voltage, connector type, and the controller part/model number to ensure fit. The kit’s model and part identifiers help match it to original equipment or compatible aftermarket systems.

• Controller model number: HB3650-TYD6-FS-ROHS; part number W15165070015.
• Rated system voltage: 36V — suited to 36V battery packs only.
• Throttle: 6-pin male connector — verify against your vehicle harness.
• Wire gauges: 14AWG power lead, 20AWG control wires for OEM-style robustness.

Who this is for: Riders, repair shops, and DIY mechanics seeking a reliable replacement controller and twist-throttle for 36V Razor dirt bikes and compatible scooters. Choose this kit if you need a component that restores responsive throttle control, adds overload protection, and matches common wiring standards; if your vehicle uses a different voltage or connector, opt for a model specified for that system instead.
