Grin Products

	All-Axle Hub Motor The All Axle motor takes the simplicity and robustness of the direct drive hub motor, and optimizes it for the modern bike platform. This hub is fully compatible with all quick release and thru-axle bike forks, it is over 30% lighter than standard generic hubs of similar power (4kg vs 6kg), and can be used in single side applications too.
	Baserunner The Baserunner is a slim profile field-oriented motor controller that fits inside the baseplate of popular downtube battery packs. This product is based around ASI’s BAC355 controller platform ,but is configured and connectorized to be much easier to wire up in an aftermarket ebike.
	Battery Anchors Many aftermarket ebike battery packs don’t come with the best hardware for securing them to the bicycle frame. We’ve tackled this problem with a range of machined aluminum battery anchors that are much more versatile, from the popular double and triple bob’s to more specific solutions for things like the eZee flat packs.
	Cycle Analyst V3 The Cycle Analyst display is our first flagship product released in 2006 and now in its 3rd generation. While the hardware design may be showing its age, it still has capabilities and functionalities that are unmatched by modern ebike systems with their pretty colour screens. This device also serves as an educational tool so that people understand the nitty gritty of how their ebike is performing, while adding all kinds of customizable control features to tweak your ride.
	LiGo 10X Battery The Ligo10X Battery is our next generation of air travel friendly 99Wh battery pack that can be stacked together into large packs as required. It replaces the original LiGo modules that we made from 2016-2021 with a new form factor, integrated mounting rail, integrated connectors, and latching clip mechanism.
	Loadrunner (Wheelbarrow) The Loaderunner is a retrofit kit for wheelbarrows using a motor with a super high 30:1 gear reduction ratio. This kit includes special mounting brackets and hardware to readily retrofit almost any straight handled wheelbarrow with an electric motor that can pull loads up the steepest hills with ease.
	Phaserunner The Phaserunner was our first major controller partnership with ASI to bring their high performance field-oriented controller platform into a form factor and connector standard that worked well with ebike systems. It can support up to 72V nominal batteries and works well with systems running upwards of 2000 watts.
	Satiator The Satiator is a fast and powerful universal battery charger that can be configured to charge a multitude of different battery types and voltages. It allows for partial charging to increase battery cycle life and has an OLED display screen to show realtime charging statistics. This is one of Grin’s most revered and popular products.
	Statorade Statorade is a specially formulated ferrofluid that improves the thermal performance of direct drive hub motors. Just a small amount added to the motor magnets can double the thermal conductivity of the core, allowing the hubs to be driven harder and longer before risk of overheating.
	Superharness The Superharness is a special smart cable we produce that hooks up to the Main9 plug of our V6 Phaserunner or Baserunner motor controllers support 3rd party ebike displays and various modes of proportional regen.
	Torque Arms For every force there is an equal and opposite force, and for every torque there is an equal and opposite torque. Sadly with import hub motors this opposing torque is often born entirely by bicycle dropouts that are not up to the task, allowing the motor axle to spin out. Grin has pioneered the design of aftermarket torque arms to transfer this axle reaction torque safely up to the bicycle frame and away from the dropouts.
