Tidalforce iOX front disc brake upgrade

Since the black Tidalforce iOX Cruiser's front battery hub is dead, I thought I'd swap out the front wheel with a disc wheel with the Schwalbe Big Apple tires while I fix the front hub battery. Since the wheel does not have a caliper brake rim, I had to install front disc brakes on the iOX. It wasn't difficult. I had to go to my local bike shop to get a brake cable cut to length but that's all that was required. The wheel already had a 203mm disc rotor installed. I used the appropriate adapter for the Avid BB7 disc brakes and the bike was upgraded in no time.

I like the look of the iOX with the new wheel. It looks sleeker and lighter.

RIding impressions of the Tidalforce iO Step-through cruiser

I decided to take my newly assembled Tidalforce iO Step-through bike to work since I rarely have the opportunity to ride it after work and on the weekends. I keep it in the securely locked and watched bike storage locker at work. The day that I rode, the weather was perfectly. Warm, but not muggy and the sun was overcast.

Like all Tidalforce bikes, the iO Step-through (iOSt) has a perfectly silent motor and the ride is as smooth as silk. The riding position is very upright and kind of reminds me of an old-fashioned european bicycle. You're meant to ride it strictly for leisure and not for speed. The seat is a bit slippery so I tended to have to center myself every once in a while. I need to fine-tune the seat height and handlebar position more.

I used my Bosch Fat Pack with only 3 of the packs so theoretically had 6Ah of power. I used up 4 according to the Cycle Analyst and it still felt very strong. I rode in both regular (12.5mph) and Turbo modes (19.5mph). The regen worked as advertised and did a great job as both a braking device and power generator.

Overall, I look forward to more rides to get a break from the office.

More later,
Ambrose

Tidalforce iO Stepthrough from parts

After lacing the motor into the Alexrim wheel, I thought I'd just continue and finish up installing the motor into a Tidalforce frame and completing the bike! Presenting a newly assembled Tidalforce iO Step-through from various leftover and new parts. I plan on taking this to the office and getting some rides in during the day. The rear tire is a new Sunlite 26"x2.4" Schwalbe Big Apple clone. That's the Schwalbe Big Apple on the front wheel for comparison. You can see that the Sunlite does not have the nice reflective ring painted on the wheel. I eventually replaced the disc front wheel with a cheap rim brake wheel that I picked off a neighborhood kids bike that was about to be thrown away.

Laced a Tidalforce motor into a new Alexrims DM18 rim

I had about an hour and I laced my old rusty Tidalforce standard motor into a new AlexRims DM18 rim. I used my cheap custom made Klein Rapi-Driver spoke nipple tool. It was amazingly easy with the Park Tools truing stand. I do need to make a larger base for the Park Tools stand since it's not designed for such heavy wheels!

I bought the motor from a gentleman who bought the whole Tidalforce iO Stepthrough with a dead battery and decided to just toss the motor and battery and control cables. I'm happy to have it, even though it needs a bit of TLC (paint and derusting).

What was really shocking is that with the Klein nipple tool, tightening the individual spoke nipples provided an automatic torque control, essentially. Whenever I got to where the spoke was coming through the nipple enough for it to be fully seated, the spoke would force the nipple tool to unseat from the slot so that it would stop tightening. I only had to tweak two spokes afterwards to true the wheel. Brilliant!




I definitely need to derust the torque arm before too long!

Don't do an Alec Baldwin, err, I mean, Salmoning in traffic!

Here's a very informative article on new urban bicycling terms useful for when you ride your bike to work on the 16th of May!

Batch of Controllers

I picked up an assortment of dead and working electric bike controllers over the last week. They are a little bit of everything.

A Lyen 9 FET mini-monster controller.
A 12 FET Infineon controller
A 15 FET Infineon controller
A 12 FET Crystalyte sensorless controller

Then another couple of controllers showed up on Endless-sphere.com.

A 12 FET 36-48V 30A controller
A 12 FET 48-84V 35A controller

These are supposedly sensored/sensorless which would be very handy!

Pix below. Can you spot which one is which?
