XRT Moto manufactures Purspeed bikes and maintains complete parts inventory for the full lineup: 12-inch (24V), 16-inch Eko (24V to 36V), 16-inch Xtreme (36V, 25A controller), and 20-inch (36V to 48V). The catalogue covers 24V to 48V LiFePO4 batteries, 150W to 350W motors, 15A to 25A controllers, 140mm disc brake systems, suspension fork upgrades, throttle assemblies, seat and handlebar components, and 12-inch to 20-inch tires. Purspeed parts share architecture with XRT Moto and Thumpstar bikes using Anderson PowerPole and JST-SM connector standards.
What Purspeed Parts Does XRT Moto Stock?
Purspeed parts at XRT Moto: 24V to 48V LiFePO4 batteries with BMS, 150W to 350W brushless motor assemblies, 15A to 25A controllers with model-specific power curves, 140mm mechanical disc brake systems, front fork upgrades (30mm stanchions, adjustable air preload), throttle assemblies (Hall-effect sensor), seat assemblies, 22.2mm handlebar components, CNC foot pegs, and 12-inch to 20-inch Black Cat tires with Schrader valve tubes.
From our experience with the Purspeed range, the 16-inch Xtreme generates the most technical enquiries. The most common question is whether XRT Moto spec batteries fit the Xtreme. In our workshop, the answer is yes in the majority of cases when 36V voltage and Anderson PowerPole connector specification are confirmed.
What Voltage Do Purspeed Bikes Use?
12-inch: 24V, 20A controller. 16-inch Eko: 24V to 36V depending on model year, 20A controller. 16-inch Xtreme: 36V, 25A controller. 20-inch: 36V to 48V depending on configuration. Confirm from battery sticker. Chargers: 24V 2A, 36V 2A, or 48V 2A — must match voltage exactly. Installing a 36V battery on a 24V Eko controller destroys it immediately.
The most preventable Purspeed failure we see is controller damage from wrong voltage battery installation. A 36V battery on a 24V Eko controller fails within minutes. Read the voltage sticker before every Purspeed electrical order.
Are Purspeed Parts Compatible With XRT Moto and Thumpstar?
Yes. Purspeed parts share factory specifications with XRT Moto and Thumpstar. Most electrical components cross-reference with XRT Moto and Thumpstar equivalents on matching voltage systems. Anderson PowerPole battery connectors and JST-SM signal wiring shared across all three brands. Verify specification and voltage before cross-brand substitution.
In our workshop, Purspeed cross-compatibility with XRT Moto components resolves the majority of battery, controller, and motor replacement cases on matching 36V systems without modification.
What Are the Most Common Purspeed Parts Failures?
Throttle assemblies (Hall sensor degradation), battery packs (300 to 500 cycle capacity decline), brake pads (replace below 1mm), tires and tubes, and charge port assemblies (moisture intrusion). Throttle Hall sensor failure produces erratic low-speed response as the primary symptom and is the highest turnover repair in our workshop.
From our experience with Purspeed throttle failures across the 16-inch Xtreme: the symptom is almost always erratic low-speed behaviour with no consistent throttle response. An OEM replacement throttle resolves this in the majority of cases.
How Do Purspeed Parts Prices Compare to Dealer Retail?
XRT Moto manufactures Purspeed bikes and sells parts at factory direct pricing. Dealer and marketplace channels apply retail markup to every component. Buying direct from XRT Moto removes this margin entirely, providing the most affordable access to OEM spec Purspeed parts. This applies to all component categories without exception.
Parts by Category
Batteries and Chargers
12-inch: 24V LiFePO4, 24V 2A charger. 16-inch Eko: 24V to 36V, match charger to battery voltage. 16-inch Xtreme: 36V, 36V 2A charger. 20-inch: 36V to 48V, charger must match. Anderson PowerPole connections. Store at 60 to 80% charge. Never store depleted — deep discharge causes permanent cell damage.

140mm mechanical disc, single-piston calliper, semi-metallic pads (replace below 1mm). 12-inch: 12x2.35-inch at 12 to 15 PSI. 16-inch: 16x2.35-inch at 15 to 20 PSI. 20-inch: 20x2.35-inch at 15 to 20 PSI. Schrader valve tubes throughout. Threadlocker on motor mounts and handlebar clamps.
Frequently Asked Questions
Why are Purspeed parts more affordable at XRT Moto?
XRT Moto manufactures Purspeed bikes and sells parts at factory direct pricing with no dealer or retail markup — consistently lower than any reseller source for genuine OEM spec components.
What voltage do Purspeed bikes use?
12-inch: 24V. 16-inch Eko: 24V to 36V (confirm from battery sticker). 16-inch Xtreme: 36V, 25A controller. 20-inch: 36V to 48V. Wrong voltage battery destroys controller immediately.
Are Purspeed parts interchangeable with XRT Moto?
Yes on matching voltage systems. Shared factory specifications, Anderson PowerPole battery connectors, and JST-SM signal wiring. Verify specification before fitting.
Is it cost effective to repair a Purspeed bike rather than replace it?
Yes in most cases. Battery, tyre, and controller replacements from our factory direct catalogue cost a fraction of a new bike. Repair is the most financially sound choice for the majority of fault scenarios.
What are the most common Purspeed parts failures?
Throttle assemblies (Hall sensor), batteries (300 to 500 cycle decline), brake pads (below 1mm), tires/tubes, charge ports. All five consistently stocked at xrtmoto.com.
What suspension upgrades are available for Purspeed bikes?
Front fork upgrades: 30mm stanchions, 20 to 40 PSI adjustable preload. Fork seal kits available. Most impactful single improvement for mixed terrain riding.
Does XRT Moto offer dealer pricing on Purspeed parts?
Yes. Wholesale pricing for dealers and volume buyers. Contact inquiry@xrtmoto.com for trade account details.
