Two little updates here, both mosfet related. First is that we have a new 12 mosfet 40 amp Infineon based controller that uses IRFB4110 mosfets and 100V capacitors, making it relatively easy to modify for 72V operation. They also come with regen already enabled. Secondly, we now have our eZee kit controllers available with the same IRFB4110 mosfets. So now it is possible to get an eZee kit with a controller that will run cooler and have no compatibility issues with 48V packs.

Starting on April 1st, we will expand our shop drop-in hours to 11am - 6pm, Tuesday to Friday, and 11am - 4pm on Saturdays. The Saturday opening especially should help with the many locals who difficulty getting out here to pick up parts. Just do keep in mind that we are mostly an engineering / manufacturing operation and online shop, rather than a retail outlet, so things are setup accordingly. 

Time to introduce version 2.2 of the Cycle Analyst, with a few improvements. Though many commented that the 1 button interface was intuitive and clever, it did have limitations as we added more and more features to scroll through. So now there is a second 'back' button which takes you to the previous screen or down a digit, and holding this second button can get you to the setup menu at any point without restarting the device.



The version 2.2 CA also uses a membrane overlay for the buttons and the window, which is better suited to withstanding rain and elements than the previous model with a glued window and a metal push button. As well, we've now moved the wires to exit holes in the back of the box instead of grommets on the side. This permits a tidier wiring job on the bicycle. We've also included extra vent holes in the back plate that serve a) to provide ventilation so that the display window never fogs up, and b) to provide an easy means of feeding wires in and out of the device for those using advanced features such as datalogging, throttle control, etc.

We now have available the custom rear carrier for the 37V 8Ah eZee LiFePO4 battery packs. This is a seat post mounted rack, so it can be installed on full suspension mountain bikes and bikes that don't have mounting eyelets. The rack has a rail system that allows the flat battery to slide on and lock into place. And the clamping mechanism features double bolts for a really tight bind to the seat post tube, to prevent the side to side swaying that often happens when seat post carriers are used with a heavy load. This carrier is now included with the eZee LiFePO4 upgrade kit.

Both the Chinese New Year and the 2010 Olympics got underway on the same day this month. Justin was in Shanghai visiting Mr. Ching at the eZee Bike factory during the start of Spring Festival, and kicked off celebrations there with his two favorite hobbies in one, pyrotechnics and ebikes!









Meanwhile, here in Vancouver the winter Olympic games and festivities are well underway. We're doing our best to keep the shop open and running all the while, but keep in mind that during some events we may be quite short-staffed or have our attention elsewhere. Things will be normal again starting March 2nd.

We've just gone live with a convenient web page to facilitate the process of building hub motor wheels. Our online spoke calculator has all the pertinent details for lacing common hub motors in a single place, so that you don't have to hunt down manufacturer spec sheets or make accurate measurements and deal with overly complicated programs to figure out a spoke length. Just choose your hub, choose your rim (or enter the ERD directly), and out comes the spoke size for your wheel.

We first got involved with torque arm manufacturing a little over a year ago, pioneering a 2-piece design that causes the motor torque to further seat the axle into the dropout. The designs have evolved based on testing and failure analysis, with thicker plate metal and improved geometries. In our original Universal Hose Clamp design it got to the point that the hose clamp itself would be the weak link to give way in the event of a spinout incident, so our latest version has now been released which includes double hose clamps and an elongated slot in the thick axle plate to fit a range of fork types.

We are offering a great deal on the 36V 8Ah triangular NiCad packs if you get them as the battery option with either an eZee or Nine Continent kit. For just $180 USD (or $200 CAD) you'll get a reliable battery that mounts discretely in your frame, gives 20-30 km of range, and comes with both a charger and MEC frame bag! This special will last until the end of January.

Our store this year will be open throughout the holidays, so you can continue to count on us for parts, service, and support. However, from Dec 20th to Jan 3rd, the staffing levels will be much reduced, so we'll ask that any walk-in customers let schedule with us ahead of time before dropping by.

We're pleased to have EcoSpeed's new Mountain Drive conversion package available and in stock for riders in Vancouver and the rest of Canada. Although our specialty has been with hub motor conversions, there are strong cases to be made for mid-drive units that assist through the bicycle gearing in some applications. EcoSpeed in Portland, Oregon, makes one of the most powerful and professionally engineered packages available, and so we were excited when they recently released a model that was compatible with upright mountain bikes and not just recumbents. It may be a while yet before we have them properly explained and listed on our store site, so for now email if interested.
