Bruce Lau has brought out the first revision of the ebike audio amplifier (VeloAMP) originally released last fall. It has now been slimmed down to half the original enclosure thickness, while still maintaining the full 100 watts of stereo output power, 24-72V input voltage, a volume knob, speaker terminals, and an indicator LED. It looks slick, and delivers volumes. These units are in stock again for those wanting to play with loud and high quality sound systems on their ebikes.

We've just become aware of a firmware problem that exists in all of our current stock of Infineon motor controllers which can present a safety risk. Normally there is a high voltage regen cutout that prevents any regenerative current from flowing as soon as the pack reaches 58V. This is incredibly important, not so much to prevent overcharging of batteries, but to protect the controller and electronics against voltage spikes that can occur when the battery pack is disconnected. With no battery attached, the regen current has no place to flow and rapidly charges up the controller capacitors until something gives. Unfortunately, somewhere in the communication efforts to try and make a more easily 72V compliant controller, this protection was eliminated from our recent batch with 100V components. As a result, if you ride the bike without the battery, or your pack becomes disconnected while riding, then there is a risk of frying the controller mosfets.



At the moment, we have suspended sales of the controllers and the Nine Continent kits until we get this sorted and have the controller boards reprogrammed. For those that already have our Infineon in the field, this issue only applies if you received it in the last 2 months, and the Low Voltage Cutoff on your controller label shows 27V. If it shows 20V, then you are OK. We will be contacting those who have the newer controllers in order to work out getting replacements delivered. In the meantime, keep your battery attached!

We have numerous Phylion lithium manganese batteries from 2009 that are delivering on our test station more like 8-8.5 Ah instead of the 9-9.5 Ah that we normally expect. In some cases it is just a small cell balancing issue, while in other instances it is more of an intrinsic cell capacity problem. However, with so much we want to do this year, we don't have the time to go through and try and tweak all of these batteries. So instead we are offering these packs in pairs at a great combo price of $795 CAD or $750 USD for those who want an extra range kit at a good deal. You'll get two lithium battery packs and bags that can hang on either side of your rear rack, a 2A battery charger, and a 'Y' splitter cable that will let you combine the two batteries into a single controller. The combined capacity is about 17 Ah, good for a solid 60+km range, and with the current shared between the pair of packs, it is OK to run this battery combo with high current 35A or 40A controllers.

We had lots of interesting submissions for the Cycle Analyst giveaway prize, so thanks to all those who gave it a shot. Picking a winner was not easy, but in the end we chose an electric tadpole trike project by Andrew Thomas in Toronto. He built this almost entirely from scratch using industrial aluminum railing parts and spare bicycle components. The setup is fully suspended, and features a pedal trailer that hitches on the back for his son ride as a converted tandem. It's powered from a DC hub motor on the rear and has a full fairing for winter riding.







Next prize will be decided on April 15th, so please keep the submissions coming to ca.giveaway@ebikes.ca . We will carry forwards previous entries that didn't win.

We are looking to hire someone full-time to join our 7-person team at the sales and reception end of our operation. Ideally this is a person who shares our passion about ebikes, and is familiar enough with the technology that they can help guide and support people to choosing the right components to work for them. Before getting TOO excited, it is a tough job that will require working Saturdays and being great at managing a deluge of phone calls, email orders, and walk-in visitors, sometimes all at once. Computer skills, good work ethic, and likability are a must. Lots of other skills are an asset too, as working in small business means wearing many hats. If this sounds like you, or someone you know, then spread the word and feel free to send a resume and cover letter our way at resume@ebikes.ca.

We receive many emails from people sharing us photos of their ebike projects, and quite often these are exceptional pieces of craftsmanship or creative ingenuity, or just humorous pieces that make us all laugh. We'd like to give our support to those out there in the community who are helping reshape how we think about getting around in the 21st century, those who are taking ebike parts and exploring outside the box.

So starting this month, we will be giving away a free Cycle Analyst every 2 weeks to the most interesting and unique ebike contraption that is submitted to us. It must be an original project that is mostly built up (so no concept drawings), and we'd like to hear your story behind it as well. Send your submissions by email to ca.giveaway@ebikes.ca, including photos of you and your homemade electric ride, and a little info about why you think you deserve the prize.



We're going to kick things off with Art Burns, from Seaforth Ontario who has been riding ebikes for several years since suffering an vision impairment in an accident. He had two scooter ebikes, but neither had the range for his planned Ontario to BC trip this summer. So the solution, he had Golectric hack one in half, convert it to a trailer, and load it high and low with batteries!

We're steadily ramping up an official "uni-shop" in the corner of our store. Our hope is to be the first shop in Vancouver to carry all the specialized gear for one-wheelers, and give the local unicycle community a chance to see, feel, and try out the equipment before they buy it. Anne-Sophie is around most days of the week to share her expertise.


On a similar note, we will be resuming the Wednesday evening unicycle gatherings down at Science World on March 31st, starting at 6:30pm then moving it to 7pm when the days get longer. We had a blast doing this all of last summer, and will continue to bring our fleet of spare unis for people to try out and practice on.

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.
