The venerable 400 and 5300 motor series that got so many enthusiasts started on ebikes has now been formally discontinued by Crystalyte (about time some would say!). The good news is that Crystalyte is now producing a new HS/HT motor series that is based on the same efficient motor construction style as Nine Continent, but with much better mechanical fit for bicycle and disk brake compatibility. For a more complete summary of the improvements see the postings on the Endless Sphere thread here.

We sampled these motors in January and have put them up on our simulator. We expect to receive our stock available for purchase in mid-July, and these will be the first bulk batch of sensored HS/HT 35mm motors delivered in North America, so that they will be fully backwards compatible with all the sensored motor controllers.

Infineon Controllers: After our recent shipment vanished in transit, we're still sorting out a situation. Our next batch when it does come will finally have a universal voltage range, so that the same unit can run from 24V to 72V batteries without any need to change resistors on the circuitboard.

eZee batteries: We have had good supply all year of the 3 battery types alluded to above, but the high range 36V 14Ah and standard 36V 9Ah options will be sold out soon, with only the 48V 10Ah battery option remaining. Next shipment from eZee is scheduled to arrive mid-July. 

In case people are worried we have fallen off the map with no news updates since February, rest assured this is not the case. Rather things have been so busy setting up our new shop space that there has been little time left for posting on the website. We'll try to summarize all that has gone on with the following updates.

We've traditionally been heavily involved activities around June, from the VEVA Electrafest to Car Free Days to Velopalooza and assorted Bike Month events. Unfortunately we've had to bow out of participating in all of these this year. But there is one new event coming to town that we are most excited about and will be a big part of. Vancouver is hosting its very own Maker Faire! We missed traveling down to the San Francisco event in May but will take part in the Vancouver event in a big way. Locals should definitely make a point of coming out to see creative DIY projects of all kinds on display.

Just a heads up that since the announcement of potential strikes at Canada Post last week, we have been automatically upgrading all Canada Post / USPS orders to Fedex ground service for shipments in North America. We will still continue to honor the Canada Post price as quoted on our website for these orders. For overseas shipments, it means we can no longer safely send packages via standard airmail, and customers will have to pay for the Fedex International Priority service instead or wait for the strike to wind down.

We're happy to announce Evan Sandercock, a 15 year old ebike enthusiast from Alberta, as the winner of our Grin Tech logo contest from last winter. His idea of a smiling electrical plug was simple and effectively captured the essence of what we do. After several months of additional doodling and consultation with a professional designer we have shaped it into the logo shown here. Congratulations to Evan who gets $1000 in ebikes.ca store credit, we can't wait to see the projects you do with it.

Those who've followed us over the past 6 years will remember that at various times we've carried multitudes of batteries from many manufacturers in all different voltages, chemistries, and form factors. This has lead to a wealth of firsthand battery experience, sometimes rewarding but mostly filled with hair pulling frustration.

We've decided for this year to simplify things (cut our losses) and just carry 3 battery choices from eZee that have proven dependable so far. The 36V 9Ah LiFePO4 as a standard option, a 36V 14Ah Samnsung LiMn pack for extra range, and 48V 10Ah Samsung LiMn for extra speed. All of these batteries in the same compact eZee flat pack enclosure casing. It's a tight form factor that we like, and there are several rack mounting options to facility secure attachment to the bicycle.

We have purchased a new spoke machine and die set specifically for cutting straight 13 gauge spokes, in order to offer better compatibility with existing ebike spokes that are typically 13g (2.3mm). These are now our standard custom spoke offering (instead of the butted 13/14 Phil Wood spokes we sold before), with Belgium made Sapim stainless steel spokes available in either silver of black oxide. These are a serious improvement over the chinese 13g spokes that Nine Continent use in their wheel builds, and for those wanting a rugged wheel we recommend having the hub relaced. 

The original small screen Cycle Analyst has now been formally discontinued in lieu of exclusively making the Large Screen units. It has been an interesting run for 5 years but the process of machining and retrofitting an off-the-shelf enclosure box to make it hold our circuitry and work on a bike handlebar has run its course. The large screen unit with our custom molded enclosure is better in nearly all regards, and because of the high demand we've been able to drop the price to match what the small screen sold for.

Use your Cycle Analyst with 12V Batteries


We also changed the standard CA board layout in May with a new regulator that allows the standard CA to operate all the way down to 10V. That makes it now compatible with the many 12V battery systems people may want to monitor (marine, solar, backup, etc.)

And use it up to 350V too!

At the other end we have also been listening to the performance electric motorbike crowd that keeps demanding dangerously higher and higher voltages. We have increased the standard upper voltage range to 150V instead of 100V, and now offer a high voltage upgrade option that goes all the way to 350V instead of 200V. The differences between the Revision11 and previous boards are summarized below:



Rev 10 and Earlier PCBs
Minimum Voltage - 15V
Maximum Voltage - 100V
High Voltage Upgrade - 200V

Rev 11 PCB
Minimum Voltage - 10V
Maximum Voltage - 150V
High Voltage Upgrade - 350V (400V survival)

We've had occasional feedback that the backlight on the Cycle Analyst can affect night vision for some people when riding in the dark. In order to accommodate those with this sensitivity, we've had the large screen LCD modules retooled to include two sets of LEDs. The standard white LED is connected by default and produces a nice and brightly backlit display. But if that is too much, then a small solder jumper to the pad labeled 'R' will illuminate a dimmer red backlight instead. This still lights up the screen at night, but with a red light that doesn't dilate the pupils.
