SPEEDBOX 3.0 for Bosch eBikes. Tuning kit Suitable for All 2014-2020 Bosch Motors Even of The 4th Generation. Smart Tuning chip of The 3rd Generation

INSTALLATION:The device itself was fairly easy to install. The unit was smaller than expected. This made fitting it easy. The hard part was getting the covers back on. The covers has small spacers which were hard to keep in place while you lined up the screws. The covers are probably not even necessary. I did not need to remove the crank.APPLICATION:I was able to get the bike to 30 mph, and it did not cut out. That is more than I need for my purposes. There is a counter that flashes .01 to .06 when you stop. I am not sure what to do, so I wait for the count down. My bike is under warranty and hope if it breaks I can fix it. I rarely go over 20mph, and if the true speed was 20 I would not need this device. More on that below.THE BIKE AND POSSBLE HACKS:I bought the Niner WFO E9. The bike was limited to 18.5 on the bike speedo. The real GPS speed was 15. I went to the dealer who was surprisingly helpful and changed my wheel size to the smallest Bosch would allow. Now the true speed limit was 16.5. I was hoping the wheel diameter change would get me close to 22 or so mph so I have some headroom for certain jumps. If the speedo was accurate the hack would work and I would not need to buy this device.PERFORMANCE ON NORMAL BIKE VS EBIKE:On my enduro I can get the speeds needed but I get tired after 2 passes. I wanted to be able to do the same jumps over and over which is why I bought the WFO E9. The climb up and the run up to the jumps ate up all my energy on my enduro. After 2 or 3 jumps I was so spent I could not do the jumps in the manner I wanted because it requires energy that was wasted on the run up. The e-bike cuts out so hard its like a wall at 15mph when I need 18 to 20 to clear and land it perfectly. I was not able to clear the jumps on the ebike until I got this chip. All I need was the right jump speed which the bike should do if it was reading accurately.MESSAGE TO BOSCH:If you are reading this at least make the 20mph limit 20 instead of exaggerating read outs. Allow it to be slightly hacked on the next update. 22 to 24 aint too much ask for.

It doesn't sound like much but the difference between being capped at 18.5mph and being able to go 23mph is HUGE. It'll feel like a brand new bike again.I know Bosch says 20mph but we all know the motor cuts off early. Then it actually fights against you. It's like slamming into an invisible wall that dashes your Hope's and dreams every friggin time.I tried the free speed hack with the tape and the magnet. I didn't like the feel of the power coming on. Since you're feeding false data to the speed sensor, the torque would come on slow at first then ramp up fast. Felt neat on the road but I didn't like it while MTBing. You lose that motor sensitivity and the bike is harder to use at slower speeds over rough terrain.Not to mention you lose your speedometer AND odometer. Then I started getting those error code 503. I know it's free and it's hard to compete with that. Or so I kept telling myself. If this is your situation, you should definitely not wait any longer and pull the trigger.Merging on the road feels much safer. I can comfortably cruise at 25mph on my Raleigh Magnus fatbike (2017). I've taken it up to 30mph pedaling 100% on a flat grade and 40mph on a long downhill. 40mph on a fatbike! I was passing soccer moms in their SUVs down H st as they watched, mouths agape, like "Who the eff is THIS cowboy?" You'll love it.It will chew through your battery. Still worth it. You just press the Walk button to enable/disable the chip. Does not interfere with any bike features.So happy. Thanks Speedbox!

The old prompts to initiate the speedbox on my Bosch Active Line Plus (simply pressing walk button) no longer is an option. I believe Bosch has caught onto this and the new firmware eliminates it. Even the, -,-,+,+ option that speedbox website says will work won’t work. The speed sensor is no longer recognized when rear wheel spins. I’ve taken the speedbox off bike and bike runs fine. Everything works. Put speedbox 3.0 back in and nothing. Bike in stand and can not get anything to function properly. Will not ride this on road without speed sensor working because I’m certain an error code will pop up as speed sensor doesn’t register and software will see no speed and kick up error code.Total bummer. Speedbox does not offer a solution and won’t admit to me that Bosch has “hacked the hack”. I have emailed them directly about a solution and have not gotten clear answer. Either avoid the firmware update or say goodbye to your speedbox. I chose the latter but not by choice.

Works 100% as advertised. Tucking the unit behind your motors plastic cover can be a pain, depending on the bike/frame type you have. I basically zip tied the cords somewhat neatly and tightened the cover.Of course everyone wants to know how fast your bike can go. I have a hard tail with 2nd gen bosch performance CX motor. It can exceed 40 mph with significant effort on my part. That said, not safe, and will kill your battery/motor. These things are just not built for that kind of duty, I measured excessive heat from both the battery pack and drive motor, unlike anything the bike has seen over the ~3500 miles I have put on so far.That said, I bought this to turn a class 1 (20MPH) ebike , into a class 3 (28 MPH) ebike and for that it works flawless. Don't listen to the reviews that say you cannot set a speed limit. The instructions are not particularly clear, but what you need to do is cycle (quickly) from turbo to eco and back to turbo. The display will flash numbers referring to max speed assist, from there you can press the walk button (intuvia display) or turn the back wheel to increase the max assist. It doesn't quite make sense (maybe to do with bike wheel size?), but for me setting the display at 2.5 = 28 mph max assist. From here it works perfectly for commuting. I put in fair effort, and the bike does as well.

Identical to the Speedbox2 in function i.e. preventing motor from cutting out at about 15 mph, except that it can be used on 4th generation Bosch motors without causing the Error 504 problem after a couple of hundred miles (motor going into limp mode). Easy to fit in 5 minutes especially if your motor cover is the type that doesn't require crank removal. Also consided the badass box as an alternative.

Well what can i say works fine for me.fitting not hard for me.Removed speed 15mph limit.Use more battary now but thats ok.

Was a little trickier to install that the video's suggested but this is more down to the bike and not the device itself. Overall great purchase - works really well - highly recommend for anyone with a compatible e-bike !

An easy way to boost your ebike's performance.

Product is excellent. Exactly as described and works really well.My only issue was the late arrival of the product despite being a prime member and paying over £5.00 for delivery it was well over a week late so a little disappointed in this and lack of tracking updates but everything else perfect
