Bosch Eplus Advanced chip


New Member
Just bought a used 2016 Cannondale Mavaro and am thinking about getting the Eplug Advanced chip to de-limit the motor and get access to fun data like wattage input/output etc. Has anyone here used one of these?? Seems like its $20-40 more than a Speedbox 2 but way more functionality!

It also claims to have a "engine immobilizer" which is neat but I wonder how that is supposed to work...

So I bought Eplus Advanced Bosch speed unlocker and here are my thoughts. The first few points are generic to really any speed unlocker:
  • I used to ride in turbo all the time and just cruise at around 19mph and I could basically just pedal harder or use less effort and the motor would make up the difference. I found once I had the speed unlocker that I would use the different assist levels almost as I would a derailleur. On the flats I find myself preferring to ride in Eco or Tour so that I don't waste tons of electricity on wind resistance and on hills I typically bump up to sport or turbo to keep my speed up. At first I was frustrated at the change in use mode but now I'm used to it.
  • I picked up a few minutes on my 9 miles commute with the speed unlocker (traditional bike commute 45mins, 20mph limited ebike 30-35 mins, speed unlocked 28-30 mins). I do have a lot of stop lights and 3 small hills.
Specific to Eplus:
  • You use the walk button to unlock the speed each time you turn the bike on.
  • Its nice that you can read battery life in 1% increments and you can see your power input.
  • The "Code/Motor immobilizer" works like this per Eplus: If you activate the immobilizer, after two rides the engine is turned off. **What I found is that if you activate the immobilizer then the computer will turn off when any wheel speed is sensed, which I actually like better than giving a thief two rides... So it just turns your ebike into a super heavy normal bike until you unlock it again. I was hoping it could do more to prevent ANY movement by locking up the motor (using the battery) like the Stromer's do but alas, no.
  • Current speed/odometer/range work per normal which is great but the trip time/distance and average/max speed all freak out and display crazy numbers regardless of whether you are riding in "unlocked" mode or not.

Overall, the Eplus Advanced is not that much more expensive than other basic speed unlockers so hopefully you find the extra features worth it.
*Edited* it seems like the Android 10 bug got fixed! Yay!
**Edited to add how the code immobilizer seems to actually work, as opposed to what ePlus told me

It seems like the bug is fixed! Also, there does still seem to be a weird issue with Google auto-fill for login user name and password so I just manually login. But it works! Now I just need to log some rides to get data!
