    Factoring in the cost of battery, labour and the bike itself, you might be better off with a pre-assembled E-bike.

      Are there pre-assembled 250w bikes where you can bypass pedal assist to full throttle when required (max motor speed/output)? I installed one of these motors a few years ago. The power/torque is fantastic and with the throttle made climbing hills a breeze.

        Are there pre-assembled 250w bikes where you can bypass pedal assist to full throttle

        To be considered a standard e-bike for legal use on public roads in Australia, a bike must meet the following criteria:

        • Pedal assistance: The motor should only assist when you are pedalling.
        • Maximum motor power: The continuous rated power of the motor must not exceed 250 watts.
        • Assistance cut-off speed: The motor's power must stop providing assistance once the bike reaches 25 km/h.
        • Weight and other features: The bike must be less than 50 kg, have an adjustable seat, and be a power-assisted cycle, according to Transport for NSW

          oh no, the poor hill, summited with nary a bead of sweat thanks to the perfidious electric motor throttle. wont somebody think of the children?!

        You want to climb a hill at 50km/hr without any pedalling?
        Then get a real motobike, and pay for insurance. And stay on the road.
        I like my e-bike, but some people have to ruin it for everyone.

      • spacemannn on 08/10/2025 - 14:51

        At that point you'll have something travelling at regular traffic speeds, without the protection required from having a motorcycle. If you wipe out or get hit by a car you'll be worse off with a flimsy bicycle helmet instead of a motorcycle helmet. Worse yet, you won't even be wearing a jacket, Kevlar pants or boots that cover your ankles. You can look up videos of the consequences and see why the gear is recommended.

      These are more likely for people who already have a bike which they already modified to their own specifics to enjoy riding. It may actually be more work to buy a new bike and have to modify, calibrate that bike.

  • toeachbyeach on 08/10/2025 - 12:26

    I have this bike and was thinking of installing a motor:

    https://www.jamisbikes.com/new_pdf/renegadeexpat_new.pdf

    I'm fairly handy and it has the right BB as far as I can tell. How hard would install/conversion be?

    • j13 on 08/10/2025 - 12:51

      Yes you just need a frame with a threaded bottom bracket which the one you linked has. Installation is at least an hour, depending on how sophisticated you want to get with routing the cables to display, whether you install the brake cutoff etc. Plenty of how to vids on youtube.

      Also, keep in mind these mid drive motors only have a single chainring whereas the bike you linked has two so you'll lose some gear range.

      • toeachbyeach on 08/10/2025 - 13:07

        Thanks for the response. I was actually thinking of removing one of hte front chainrings anyway as i never use it and i would prefer a better chain guard/cover anyway.

        Very tempted now!

          Yeah single ring is way simpler and easier to maintain. All my bikes are single these days.

          Make sure you get a quality battery with name brand cells if you get this!

          You'll need to fit new hydraulic brakes and shifters as this engine will get you going much faster while weighting a lot more than those cable calipers are meant to handle. Well… technically they'll work but the performance may not be quick enough to stop in time.

          • toeachbyeach on 08/10/2025 - 13:34

            @Pseudo User: Honestly its gonna mostly be to get me up hills without as much effort. I don't plan on fanging it around western sydney.

    • Chickenleg on 08/10/2025 - 20:43

      I've done 2 BBS02B kits and found it quite easy. Just watch out out as you may need a 2mm spacer for the chainring as it's likely to be too close to the frame.

    • shap08 on 08/10/2025 - 12:39

      considers it doesn't have a battery this has zero risk of fire.

      Also one of the best R&D ebike motors you can buy. https://electrek.co/2025/02/17/i-went-back-to-bafangs-factor…

        Without battery it will just be a giant paperweight, in which case, FREE rock will be a better alternative than spending $499.

      • DashCam AKA Rolts on 08/10/2025 - 12:46

        eBike with no battery…interesting.
        Also…

        Rated Voltage: 36V / 48V

        • shap08 on 08/10/2025 - 12:59

          Yes that is what it can handle, just purchase a local compliant battery and you will be fine.

      Does your car come with a first aid kit? 1300 deaths last year!

  • toeachbyeach on 08/10/2025 - 13:19

    Is this legal when installed as per the two legal e-bikes:

    Power-assisted pedal cycles
    A power-assisted pedal cycle:

    has one or more motors attached with a combined maximum power output of up to 200 watts
    can't be propelled only by the motor/s
    weighs less than 50kg (including batteries)
    has a height-adjustable seat.
    Electrically power-assisted cycles
    An electrically power-assisted cycle has a maximum continued rated power of up to 500 watts. This power output must be:

    progressively reduced as the bicycle’s speed increases beyond 6km/h
    cut off when:
    your bicycle reaches a speed of 25km/h
    you stop pedalling and the speed exceeds 6km/h.

    • toeachbyeach on 08/10/2025 - 13:36

      Of course they have. Couldn't they just make it so you have to seperate the battery from the bike? I finally found a decently priced alternative to my car that I can no longer afford and nope can't have that either. Guess I'll just sit at home and die.

      • schquid on 08/10/2025 - 13:51

        Fair. Actually riding a bike, what with your leg muscles and such, is a fate worse than death. I hear tell the redesigned Hell 2025, coming in 2026, features endless rolling hills you get to ride a bike around on.

          • schquid on 08/10/2025 - 16:33

            @toeachbyeach: Then you can claim an OTS ebike purchase with NDIS, they provide funding so long as it's a justified acquisition. You could get a far better spec, fully compliant ebike rather than using a dodgy bolt-on kit.

      • edfoo on 08/10/2025 - 18:10

        You can still buy and get your e-bikes on the train if they are already made and being sold here in Australia.

        • toeachbyeach on 08/10/2025 - 18:15

          Yeah I'll look into it. Just sucks I have a bike I love but wanted some power for hills. It's a whole other thing to get a new bike and not a fun project haha

          • edfoo on 08/10/2025 - 20:29

            @toeachbyeach: You should know NSW has maximum electric motor power limit of 500W (up from 250W previous years) on public roads and paths anyway. I know there are many illegal e-bikes around with >500W motor and top speed over 25kph, so why should you need more than 500W power? If the hills are so steep that you need >500W to climb up, maybe you should not be going up that hill in the first place.

            • toeachbyeach on 08/10/2025 - 20:36

              @edfoo: Thankyou. I have decided I will keep my eyes open for a couple different bikes which are approved based on all the new rules. From what I can tell I'm happy with 250w but as I eluded to I was hoping to get rid of the car so I was hoping to get a bike that I could pickup groceries in and run errands/travel decent distances when public transport isn't available/appropriate.

  • bargaino on 08/10/2025 - 13:37

    Folks, as far as I can tell, this motor has no torque sensor , which if true, makes this a very bad choice.
    Can anyone confirm?

    Most commercial mid-drive e-Bikes do have such a sensor, and most hub-drives do not. This is the biggest reason why mid-drives feel much better to ride.
    Without it, the motor has a fixed power, not affected by how hard you pedal.

    • danmc64 on 08/10/2025 - 14:34

      Yeah its cadence sensing.

      In my experience the difference is minor, especially if commuting.

    • danwylie on 08/10/2025 - 17:06

      I've tried both and in the city I prefer this style, but it depends what sort of help you want. If you want a boost to your current effort, like you want to go further for the amount of effort you're putting in, then torque sensing is better, if you're mountain biking I think its the only way to go. But if you just want a certain amount power to go into the wheels, which you can dial up and down, then these are better.
