New S-750X upgrade in the works

I was recently contacted by a former executive of Wavecrest Labs to do an upgrade/repair of their Tidalforce S-750X bike. He was interested in having his throttle repaired and upgrading the bike to a 20AH battery pack along with the Cycle Analyst SA and an Avid BB-7 front disc brake upgrade.

I have the bike and have started working on it.

Here's the bike as it was delivered. The front hub battery is dead. The throttle was busted. Everything else was quite beautiful!


Here are the parts I speced out for the upgrade boxed up! LOL.

In the box are a Topeak MTX rear rack, an MTX rear bag, the 16AH batteries. (HobbyKing was out of the 20AH batteries). The Cycle Analyst. What's missing is the Avid BB-7 disc brakes.

Here's what I've done so far.

The Cycle Analyst is mounted, the rear Topeak rack and bag are mounted, I've removed the wiring from the front fork. I've run the Cycle Analyst sensor/controller wire through the frame. 

I've also added the Delphi connectors to the Cycle Analyst shunt.

I'm having the original Alexrims G3000 front wheel converted from the hub wheel to a disc brake wheel so have bought an Shimano front disc hub and need to figure out the spoke lengths for it and buy them and lace them.

More as it happens.

New E+ Electric Folding Bikes in My Stable!

Well, my neighbor that I met a few years ago sent me an email and said that he no longer needed his 2 E+ folding electric bikes. They are custom bikes mounted on Downtube 9FS frames which are very sturdy and solidly built. He had kept them in his shed so they need a bit of cleaning up, however, both batteries seem to be in good health. Amazing. I'll clean them up and post some after pictures but here are a couple of before shots.

New Tidalforce M-750 project

Well, it’s Spring and I need a new project. I have had this M-750 frame in storage for many years. I bought the frame from a former employee of EMS when they went out of business. They had some left over frames from Wavecrest Labs when they went under. I bought a couple from him and kept this one.

I have a new job in downtown Washington DC and the Tidalforce M would be a great commuter bike. I have a new battery and plenty of parts to put this together. So here goes!



This is pretty much the way the frame came to me. I added the double kickstand and wired up the console and cabling. I also mounted brakes but I plan on changing the front V-brakes to disc brakes.

Picture of most of the stable of TF bikes...


The weather is warming up and I'm hoping to be able to ride my bike to work this Spring and Summer! Happy Spring everyone! (this picture was actually taken last fall!)

Nearly done with Tidalforce S-750X battery and wheel upgrade

Well, I spent last night finishing up the upgrade to Rick's S-750X bike.

I replaced the front brakes with an Avid BB7 disc brake. I mounted the Grin Technologies Cycle Analyst and ran the wires back to the mount the shunt before the motor/controller. I stuffed the Turnigy Multistar battery into the Topeak MTX bag. Ran the power to the connector on the CA shunt and powered everything up. It all went together like a charm. I was able to take it for a 10 mile ride and hit a top speed of 30MPH! The bike felt great!

Here's all the tie wraps used to snug everything down to the frame and the chainstay. It looks much better when it's cleaned up!


Here's the rear quarter view of the bike before the Cycle Analyst shunt installation.

Cleaning up and upgrading the batteries for a friend's Tidalforce S-750X

Rick dropped by over the weekend to have his S-750X upgraded from the dead front hub battery to the 16 or 20 Ah battery. He had it in storage for a while so it was a bit grungy. I've got quite a bit of work to do on it. Building the 36V pack, installing the Topeak rear rack and bag, installing the Cycle Analyst...

Went for a ride at work...

I took my bike to work yesterday since the weather was so perfect. I had a chance to take a break and went for a ride. I passed a police officer sitting by the side of the road and about a mile down the road, he sounds his siren and pulls me over! Another rider riding by said, "You're pulling him over? For what?" My thoughts exactly!

He was just curious about the bike and how it was going so fast.

I gave him a quick tour of the bike. I didn't offer to give him a ride, though...

I took my S-750C (for Crystalyte) bike. Crystalyte HS3540 motor with the Multistar 16Ah pack. It has the eBikes.ca BAC500 FOC controller and a Cycle Analyst V3. I also have eBikes.ca lights front and rear. I have disc brakes front and rear as well.
