    Broken bolts on Bosch CX motor

    TS25 (Torx security 25 with 5 point not six point). Can be replaced with standard T25 or better still TP25's However, the standard ones are quite high tensile machine screws.

    Bosch Gen4 Seal Service & Grease up

    Because the Gen 4 is really not a DIY type of motor, many people would be in for a real shock if they thought they would give this a go. There are so many issues when working on this motor, but our main concern is the plastic bushes have the consistency of an egg shell, and are a pain to fit...

    Levo Gen 3 Planetary gears! DIY??

    We have the tools and enough planetary gears for everyone! However, it did take us over a year to perfect the tool and learn how to get the angle magnet out and back in perfectly.

    Bosch Gen4 Seal Service & Grease up

    Sadly, it's not possible to fit all this in situ because the seal situated behind the plastic washer has a steel band that tends to be bonded on the early motors, and corrodes on the later motors. Getting this part out, and cleaning it up to receive the new parts, would not be possible. Also in...

    Don't worry, it's no riskier to remove the PCB whether its old or new. What manufacturers should stop doing is fitting PCB at the bottom of the motors!! Yamaha for example have a thick coating on the PCB, but then fit it at the bottom of the motor, in the water! The water then eventually soaks...

    It would be a great idea to coat these boards, but in many cases the board is soldered to the motor and would be a nightmare to coat. In other cases (including Gen 4) the motor case is used as cooling for the board, this part could not be coated due to temperature transference and this is the...

    No real conformal coating. But don't forget, manufacturers say that the motor is sealed, so wouldn't need a coating :rolleyes:

    Absolutely 😂 We had a small batch of everything manufactured for testing. After testing we had a few left over and this is what we used to keep you one step ahead of everyone else :)

    The wait is over! A more comprehensive explanation, reasoning and price will be on our website as soon as I have time. I cannot confirm a price on here as prices change, but in the UK this should be just under £200.00 Please note, the parts are not that expensive, but this motor is extremely...

    😂 Don't worry, you have all the good stuff in your motor 😎 With SS bearings it's more a case of finding them in the right size, with the right seals, at the right price! It's just not possible. For the reasons @Spiff stated above, but also with ceramic bearings, there are very few sizes made...

    Quick question: Does anyone here have a relatively loud motor whine when they get to the 15.5mph cut out?

    It would definitely help! But not possible on motors that are not currently designed for it. This is a great video, but missed the real reason motors fail. Putting aside pressure washers etc. As we all know, you can ride your emtb through deep water and nothing happens, it will appear to be...

    Levo Gen 2 Are Brose & Specialized Fixing Their Motor Problem ?

    Three reasons to not use O-rings on the crankshaft. 1, An O-ring is classed as a "static" seal. If used on a rotating part it will wear quite quickly and when dirt and grit are added, the O-ring cuts into the motor housing and crankarm. 2, If the motor has been used, then there will already be...

    @Bearing Man "All parts are available from us except the PCB" …Could you please clarify Pete, do you mean "all parts" and would these be 2nd hand from written off motors with corroded PCBs? i.e. to repair one customer's motor with a faulty sensor there has to be another customer's written off...

    When I bought mine during lockdown, I assumed buying a Bosch powered EMTB was a sensible thing to do due to the company size and reputation. You made a good assumption, Bosch have an excellent reputation for good customer service with a very fair and generous warranty system. I assumed the...

    I fully get what you're saying Planemo, and I agree with much of it. As said before, I am not standing up for the manufacturers, they are capable of doing that themselves should they want to, but I did used to work for a very large corporate company as a technical engineering manager, so I can...
