Hi all, Interesting development with the Flow app here. While I've always suggested disabling GPS/location when using the megabobra, this update from Bosch means you can't access the Ride screen without location being enabled. Not an issue once you're up and running (as long as you don't intend...

Just noticed that I can no longer view the Ride Screen without turning on location services on my Android device. Anyone else noticed this? I've never been keen on sharing my location with Bosch, to/from home etc, but want the ride stats. So I'd just dismiss the request to turn on location...

That's all correct guys, thanks for the kind words. There's seven currently in line for a device, and I'll make a few extras for any later requests. But yes, sadly it'll still be a few weeks before I receive everything and get them assembled. @mwagE, reach out if you're interested.

Same thoughts exactly!

Because there is no rim magnet sensor :) Instead there's a hall sensor within the motor case itself!

Got it, thx vm!

I've spent some time sourcing components that would be needed for this project and worked out some costing. This would comprise all necessary components to install the Megabobra to replace the rim magnet, including the genuine Bosch LPP cable to plug into the motor: Arduino loaded with...

For those who have been following the existing Derestricting bosch smart system thread, this will be old news, but I figured it be a good idea to branch the build of the Megabobra device into its own thread to manage questions without cluttering the existing topic. Quick Refresher: The...

That's an excellent idea! Definitely give that a go! 😎

Ahh understood, I'm following now. Sorry, I'm not sure. My thought is that yes, the arduino is certainly capable of doing what you need, with a quick code update of course. BUT it depends on what the existing bosch speed sensor is doing - it may not just be a simply reed switch. Since you...

Hi Ashley, The high power port, HPP, will work just as well as the LPP but you'll need to get it turned on by the dealer. 3.3v will run the Pro Mini, but I'm not sure it'll be enough voltage to drive the coil and generate a sufficient magnetic field for the motor. There's no harm in giving it...

Thanks for all the posts and messages with interest in the megabobra. I've spent some time sourcing components that would be needed for this project and worked out some costing. This would comprise all necessary components to install the megabobra to replace the rim magnet, including the...

Hi Ashley, Yes I believe that will work fine. We discussed this method a while back in this thread when someone else mentioned their existing disc sensor setup. Sadly though I don't have a bike with a disc sensor to test it on and I'm not sure the other guys in this thread ended up pursuing it...

Hi guys, For those of you with the rim magnet: I've got something worked out to assist with the alignment of the electromagnet used in the Megabobra derestricting device. Seems like some of you who have tried the Megabobra already have had great success with it, but I know I've found the initial...

Ha that's such a great idea. I've lost count of how many times I've stood holding the wheel off the ground so I can spit it an watch the display!

With the coil, more current doesn't mean a greater magnetic field. A better way to achieve that is with more turns of the copper. So where maybe you have 10m, use 20m - you should see an increase in your magnetic field strength, increase in your resistance and decrease in current. However, you...

Yes that's correct.

You have the magic touch for the placement - still takes me ages to get it settled in the right place! Yes at 2.4Ohms you will be pulling way too much current: V=IR, @ 5v you're at 5v/2.4ohm = 2.08Amps! From memory the 2222 transistor's current limit is ~0.8A.

Hey Sander, the thing to check here is the resistance of your coil - probably it's too low so it's pulling more current than the transistor can handle. Ps I know what you mean with the placement, it's a pain that it's so sensitive. It's hard not knowing exactly where the sensor in the motor...

Looks outstanding with the 40's. What do you estimate the maximum turning angle is, where say 0deg is straight ahead and 90deg is wheel perpendicular to frame? Also with the decals, I've got the standard black decals on my v1 still but some of the sharp edges (particularly the points on the...
