Testing the new Tidalforce motor in TURBO mode

I forgot to test the new motor in Turbo mode. The previous video and test was done in Standard mode so wasn't very spectacular. I averaged right around 260 rpm with the battery fresh off the charger and with the throttle wide open. With this test shown below, I used the motor in Turbo mode. The batteries were slightly used so they didn't have quite the same punch as when they're fresh off the charger.

I was surprised at how fast it was. 830 rpm is shockingly high compared to 260 rpm!!! :)

I can't wait to put it in a strong rim and with some great tires! I've wanted an X motor for a very long time and am overjoyed that I finally have one!

More later,

Testing the new Tidalforce motor and batteries Part 1

I put the motor onto the Tidalforce S-750 frame to test them this evening. This is a quick video of how they perform in standard (non-turbo) mode. I used my Cycle Analyst Standalone and a digital tachometer that I saw on Mythbusters and just had to buy one after that! It's VERY handy.

Be sure to check out my next post. There's a HUGE surprise. Don't go until you see this video though. :)

New Tidalforce Batteries and Motor!

I bought 2 new Tidalforce front hub batteries and a Tidalforce motor over the weekend for an excellent price. All are in excellent physical shape, except the batteries are missing axle spacers which I didn't photograph. Kind of critical, however, I'm more interested in using them for spare parts. The motor is complete and in excellent condition. I plugged it into a working battery and it spun up very powerfully. I'm wondering if it could be an X version. It would be wonderful if it was. I will put a skewer on it and compare it to the stock 750W motor to see if I can spot the difference. I believe it is an X motor because of the added stickers on it. Here are some pics.

The Tidalforce motor is on the left. One battery, missing the wire guide is in the middle and the other battery is mounted to my new red Tidalforce S-750 fork.

The Tidalforce motor has an unusual sticker on it. It has "122510-01 A" and what looks like a serial number of "00429".

 The first Tidalforce front hub battery missing the wire guide.
 The sticker on this battery states "122508A" "03190 PCB REV 3 05/31"

The other battery states "122508 A" "03260 PCB REV 3 05/31"

Here's the second battery mounted in the S-750 for testing. If either one is working, I'll probably remove the guts and put it into one of the other two TF front batteries that is dead.

More later,

Since I've purchased 2 Tidalforce bikes recently, I've realized that I need to sell my current ebike in order to have room to work on the two new bikes. So, I've decided to sell my favorite bike and power system.

Here's what I'm selling. I'm breaking into two separate group of items.

First, the bike:

  • Tidalforce S-750 frame 18" frame
  • e-BikeKit.com 9C motor with disc brake rotor (nominally rated at 500W)
  • Lyen's 9 FET 35A mini-controller

Stolen Paratrooper Bike!

This is quite despicable. I saw this on my local Craigslist and had to repost it. It seems that we have an active duty army soldier who had his Montague Paratrooper bike stolen from the metro. It's pretty obvious that it's a military bike since it has the very large "Paratrooper" logo painted on the frame!

It should be fairly easy to find and return if the thief doesn't alter the look of the stolen bike.

Here's the wording:

Avoid scams and fraud by dealing locally! Beware any deal involving Western Union, Moneygram, wire transfer, cashier check, money order, shipping, escrow, or any promise of transaction protection/certification/guarantee. More info

My Mountain bike was stolen from the Dunn Loring Metro Station yesterday and I would like to have it back. I deployed to Afghanistan and Iraq several times and used the bike as part of my assigned mission. This is very sentimental. No harm no foul. I live in vienna and will let you know where to drop it off.

A picture is attached below for anyone who sees it or knows who has it.

My Bike has the large Black Paratrooper letters on the side.

More pix of the RED Tidalforce S-750

I have a few more pictures of the bike. The pictures don't really show how intensely red the bike is. You have to see it in sunlight or at least bright light to believe it...

First shot of the RED S-750

Here's the first raw picture of the very red S-750 complete bike I picked up today! I haven't cleaned it up yet. It was raining pretty hard and there are specks of mud on the frame and tires. It's also missing the seat post clamp that holds the seat up. Otherwise, it looks pretty complete.

Picked up my 2 new Tidalforce bikes today!

I went out to Dulles, Virginia today and picked up my two new Tidalforce bikes today. The M-750 frame is essentially brand new. It still has the shipping wrapping on it. The S-750 is slightly used and the bike has some surface scratches on it. However, the color of the bike is absolutely beautiful and radiant! I don't think it will show well in pictures, but it is a deep luxurious red. I knew I should have built my first S around the red frame! :)

Pictures to come shortly.

Short ride on my Tidalforce iO

It was a beautiful and warm Saturday here in the Washington, DC area. I took my Tidalforce iO cruiser out for a spin around the neighborhood in the late afternoon. The iO is so smooth and quiet, although you'll hear an annoying rattle in the video because I didn't mount the GoPro tightly on the handlebars. I hope to pick up the S-750 and M-750 on Wednesday.

West Mountain CBA II

Well, I decided that I needed the West Mountain CBA analyzer I sold recently after all. It's a single purpose device, but it gives you a complete documented result of the battery's performance that is hard to match for the cost. I found a CBA II along with the accessory temperature probe on an RC board and bought it. It should be here mid week.
