The Cycle Analyst firmware version 2.1 is now officially released through the entire line of CA products. For most users there is little material difference, the trip amp-hours and distance can now go up to 1999 Ah or Km respectively, instead of 199, and the #poles variable for CA-DP devices now goes up to 99 instead of just 14 poles. But for those who like to tinker, there are extra pads now used for datalogging and external control of the speed or current limit, as explained on the first announcement last year. For those who are in and out familiar with microchip programming, the hex code is available for download here.

On the subject of Cycle Analysts and data logging, we now have a cable assembly prepared that enables you to record the data coming off a CA into your computer or laptop through the standard USB port. This device requires soldering to the Gnd and Tx pads on the Cycle Analyst circuitboard. It includes a built in serial -> USB converter, so it will show up as a COM port on your computer and the data can be viewed and logged with hyperterminal or any other standard terminal program.

It seems that a lot of people who were purchasing the high current Cycle Analyst models did not already have a shunt on hand, so we are now carrying a large 0.25 mOhm shunt that is suitable for 200-300 amps of continuous current and up to 600 amps peak, which will cover a wide range of large EV applications. This part is listed on our accessories store page.

We have also sourced a great metal enclosed 12V halogen light series that mates perfectly with our DC-DC converters. So for those who want more brightness than the LED lights, these halogen lights with a 12V DC-DC will command more than just a presence on the road. We have both 5W and 10W bulb options available, and will be releasing a dual light in the near future that will give up to 20W of illumination. 

There is finally an answer to those who have been turned off the rear conversion kits because it meant downgrading from a 9 speed shifter system to 7 or 8 speeds in order to accommodate a screw-on freewheel. The company which produces our 11 tooth 7 and 8 speed freewheels now makes a 9 speed version as well, which we have in stock with an 11-32 tooth gear range. It is of course a bit wider than the 7 speed freewheels, so most installations will require spacers on the axle and some spreading of the dropouts.

The e-brake lever is a device designed to cut power from the motor controller as soon as someone squeezes on the brakes. It's a sensible safety idea, but we stopped carrying them several years ago because the quality of the actual brake levers was so poor that in several cases the lever arm itself failed, leaving the rider without an operable hand brake. Well we now have a decent quality all-aluminum e-brake lever for the eZee kits. It plugs into the 4-pin PAS connector and effectively disables the throttle power when you are squeezing the brakes. It could be easily adapted to other controller systems as well. The switch mechanism is a magnetic reed device mounted outside the housing, normally open, which closes contact and the levers are pulled.

It turns out that trying to include a waterproof on/off button in our fully epoxy potted bike lights posed some interesting challenges. But few thing will phase us, and after a lot of work we've managed to sort through all the challenges and are re-introducing the button LED lights by the end of this week. The rear light is now slightly larger and brighter with 8 LEDs, and both the front and rear lights feature onboard memory as well. When the light is powered off, it remembers what mode it was in (on, off, or flashing) and returns to that state when power is re-applied. Pressing the button then cycles through each of the modes.

Our spring 2009 shipment of Nine Continent motors was unpacked this week and includes a few new items. In addition to replenishing the stock of front 20" wheels, we have also added to the mix:

• 26" hub motors with the higher-rpm 6-turn winding (what we call the 2806 hub)
• 20" rear hub motor with 6-turn winding
• 700c rear motors with the 7 turn winding

Our stock of Crystalyte products is generally low and the next shipment will not be arriving until late June. This shipment and all future ones will contain exclusively the Crystalyte disk compatible hub motors, so front and rear 5300 series, and rear 400 series wheels. The non-disk motors will be discontinued. As well, we will no longer be carrying the Crystalyte immediate start controllers, in either 20A or the higher power 35 and 48A devices. The Crysatlyte DC hub motor has also been discontinued, but we will continue offering the DC motor controller since it finds many applications with other motors.

This coming Wednesday at 7:30pm, Justin will be giving the first full length talk about the coast to coast electric bicycle trip he completed last summer. The format will be a mix of video and slide show, compiled from the 23,000 pictures that were taken once a minute from the handlebar camera on his bike. It will cover the trials of touring by electric bicycle and the fascinating people encountered and places explored. Anyone interested to hear more should check it out and learn about VEVA as well. The event is held at the SE1 cafeteria building at BCIT in Burnaby. Be sure to print the map or make good notes because the exact building can be confusing to find on the BCIT campus.



Also, the March kilowatt-hour ebike ride was another blast, with a turnout of 14 riders who all biked out together for drinks on Granville Island.
