New Tidalforce M-750X bike sold!

A very nice gentleman bought my bike! He will have a friend pick it up so I don't need to pack and ship it, which is greatly appreciated.

I hope the new owner enjoys his new bike!

Pics of my completed Tidalforce M-750X with my Bottle Mount Battery

I finally completed (to my satisfaction), my "NEW" Tidalforce M-750X electric bike with Avid BB7 front disc brakes and my modified battery water bottle mount. I should just call it my battery mount from now on. I bought the NOS (new old stock) bike frame from a former Tidalforce/Wavecrest Labs employee who was working for EMS when EMS shut down. He had these to sell so I bought a couple.

The bike feels very well balanced and not back heavy (as is the case with a rear rack mounted battery). It's nimble with the lower front wheel weight and lower center of gravity. As is the case with all Tidalforce bikes, it's extremely smooth and totally silent.

I am planning on putting this bike up on eBay shortly so keep your eyes open for it!

First ride of the Tidalforce S-750C with the BAC500 and Crystalyte HS3540

Just wanted to report that I took a ride with the BAC500, CADP V3 and Crystalyte HS3540 motor on an old 37V limn battery and the combination worked well. The motor was COMPLETELY silent compared to the Crystalyte sensorless controller. It needs a bit more fine tuning of the throttle response curve but so far, I'm very happy. 

In the video below, My Gopro was mounted on the stanchion of the front fork so it picks up lots of disc brake noise which isn't nearly as bad when you're riding the bike. The motor itself was beautifully silent and very smooth.

Putting my titanium Tidalforce S-750C (for Crystalyte) back together again

The weather has finally started to ease up. I am feeling the riding bug again!

Over the winter, I've picked up the tiny Mac 7T (speed wind) and's FOC BAC500 controller. However, the Crystalyte HS3540 motor has been patiently waiting for a new sensorless controller in order to bring it back to life. The BAC500 seems perfect for the job. It is so tiny and clings to the seatpost with only a couple of tie wraps that I had to try it first.

Monday, March 9, 2015 BAC500 FOC controller with Crystalyte HS3540 motor

I put together my new BAC500 controller with my old Crystalyte HS3540 motor to see how it would work. The HS3540 is sensorless since it was damaged from the original owner.

The BAC500 ran the motor beautifully. It didn't turn the motor backwards for a second very often as is common with the Crystalyte sensorless controller. It also made the motor sound very much like a Tidalforce motor! I love the size of the controller which is quite tiny and is slightly wider than a seat post!

Here's a quick video of the setup on my rec room floor. I'm running the setup on a Bosch Fat Pack 37V pack that is half discharged...

I'm very pleased so far...
