Damaged Tidalforce motor

I received a badly damaged Tidalforce motor recently. I was curious what had happened to it. It's the first time I've actually opened a Tidalforce motor. I won't open a working Tidalforce motor since I might damage it. However, opening a damaged one seemed doable. One of the magnets seems to have hit the poles of the motor and cracked In half. That caused a catastrophic failure of the entire motor. The previous owner damaged the bearings on the torque arm side and also the seals as well. This may not be salvageable.

Park Tools TS-8 mounted on a wood base

I mounted my Park Tools TS-8 on a wooden circle to hold the extra weight of electric motors. It works well!

Ford Electric Bike sighting

I went for an afternoon bike ride on my Tidalforce iO Step-through and happened upon an electric bike shop in the neighborhood. The shop is called hybridpedals.com in Arlington Virginia. They have a shop window and in it are a Ford Electric Bike made by Pedego and also a Optibike! The Ford bike is based on an Ellsworth frame and it is spectacular looking. I need to go back and take it for a test ride and compare it against my Tidalforce iO-X bike.

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,

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.
