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. |

The Analogger is a simple data logging device that takes the serial data stream of our Cycle Analyst and saves it to an SD memory card for future study and analysis. We offer both a standard model and a GPS model that saves the full route information as well. |

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. |

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. |

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. |
|
The Frankenrunner is another field oriented motor controller collaboration with ASI based on their more powerful BAC855 capable of up to 72V operation. It is produced as a stopgap controller in between the availability of the V3 and V4 Phaserunners devices. |
|
We built the Battery Grinspector as a relatively inexpensive tool for ebike shops and advanced users that need to discharge test and characterize ebike battery packs. It is controlled with a Cycle Analyst running a modified firmware and allows you to charge and discharge the battery pack into any external load at currents up to 35 amps, and produces a full discharge curve including internal resistance measurements. |
|
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. |
|
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. |
|
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 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. |
|
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. |
|
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. |
|
The tripwire adds an electric brake cutoff signal to existing hydraulic or mechanical brake levers through a clever cable pull reed switch sensor.. This way you don’t have to replace the brake levers that are already installed on your bicycle but can instead leave them in place and add just the electronic sensor to trigger regenerative braking. |
