Feature highlights:

  • Thru-axle and QR compatible
  • Built-in torque arm
  • 11-speed cassettes
  • Integrated cadence PAS sensor
  • Made in Canada

Sadly it didn’t get a torque PAS sensor.

If you’re in the market for an electric conversion kit and you like the idea of direct-drive hubs, it probably doesn’t get better than this.

    I always like what these guys are offering, but somehow the prices always seem to go through the roof, this motor even more so. When I spec one out all of a sudden they need four figures from me, though usually I’ve ended up speccing something top notch. I’d love one of these with a torque sensing controller but I can’t see it happening.

      Indeed their in-house options aren’t cheap but then again, the difference in quality is significant. This direct-drive hub motor for example weighs full 2kg less than the equivalent imports. That’s all down to engineering, materials used and accuracy of manufacturing. The other options like are significantly cheaper. I’m running a geared Bafang myself due to its lower weight (2.6kg vs 4.2kg). The lower weight is due to the type of motor - geared vs direct-drive. The lapses in quality are obvious. For example water resistance is not great at all. If Grin make an equivalent small and light geared hub, I’d probably buy it as it’ll most likely address Bafang’s deficiencies and it might be lighter too.

    Oooh, I’m not usually super enticed by e-bike stuff, but this has me wanting to start a conversion kit project…

        I’ve never ridden an ebike. Care to explain the difference in practical terms? I imagine cadence and torque are roughly correlated, but with cadence sensors you’d have to pay more attention to your hearing?

        I’ve really no idea, like I said I have zero experience with ebikes.

          Cadence sensors detect how fast the cranks are spinning and apply power based on that, although I’m not super clear on where it detects the motion when integrated into a hub like this example. Torque sensors detect how much power you’re outputting and apply power based on that.

          With cadence sensors you can shift into an easy gear and spin the pedals and have the motor do all of the work, torque sensors add a percentage of your power and make it feel like you’re riding a normal bike but are x% stronger. In general people that are already serious cyclists strongly prefer torque sensors but a well tuned cadence sensor can be fine on a utility type bike where you’re not as picky about how the power gets applied.

          Torque sensors cost more.

            Thanks for the thorough answer! I’ll have to keep that info in mind for when my knees finally give out (or if I start a much longer commute)

              Try a reputable bicycle brand mid-drive ebike at an expo or a store if you get a chance. You may not necessarily want that but it’ll give close to the best experience an ebike can give.

            Not sure on these ones specifically but the experience of a cadence sensor for me is rapid and unintuitive acceleration. In this way I think torque sensors, despite higher cost, are much more fit for regular non-serious cyclists like me.

            Of course the comment OP should head over to a couple ebike stores and do some test rides to evaluate this and other factors for themselves if they’re able.

              I have very little experience on cadence sensors but have heard people discuss tuning them to be better. I don’t want to poopoo something I haven’t used and can believe that with proper software it can be acceptable for some uses.
