      It says 50w motor on the Aldi web page, and looks cheap and crappy. Doubt it would have much power or last long.

      • 7.8Ah battery is on the smaller side

        • +2

          36V 7.8Ah = 280.8 Wh.

          This has more than 20% bigger battery at 10.4Ah (374.4Wh), LCD display and probably looks better but costs $999.

          • @dealhunter52: @dealhunter52 Any experience with this particular bike?

            I am thinking about switching to an ebike for the commute to work. 12k's, 90% flat overall is the journey and would be 2 - 3 times a week.

              @jollster101: Sorry, I have no idea.

              I believe it has better specs on the paper compared to Aldi one, but is also more expensive.

    I've been halfway thinking of buying an ebike but am a bit wary of cheap bikes after the rash of lithium battery fires lately. Anyone know anything about how to tell what's reputable?

    • +3

      It's all about the BMS and stupid humans.

      You wouldn't leave a petrol Bowser in your car. Don't leave your Ebike or scooter plugged in ..

      Put it on a $10 timer if you have to.

      There would be no fires.

      • +6

        I just read that 1 in 3 of recent lithium battery fires in Australia were not while charging. So while it plays a role it isn't the whole thing

        • -1

          Got the article?

          Just energy packets.

          Either over charging or physical damage causes energy to "spill out"..

            @tunzafun001: This one https://www.abc.net.au/news/2025-08-08/lithium-batteries-spa…

            The Department of Fire and Emergency Services (DFES) said almost a third of the fires in WA involved batteries which ignited when they were not charging.

            • +1

              @moph: Thats an odd one. I see the statement… but then the entire article is about not leaving them on charge.

              I cant see what the battery chemistry is on this one, but to reduce your risk, keep an eye out for LifePo4 packs.
              There is a youtube battery myth busting guy who basically does everything he can to try and make a LiFePO4 pack go up in flames…but cant!

              Even cuts it in half.

              For what its worth, one of my mates is a firey and he said the majority of his calls outs are for powerboards (that are ful off fluff, then the plugs get lose and arc and ignite the fluff.

              We all still use powerboards. I guess address risk reduction - chose the best chemistry lithium, dont leave it on charge, store away from combustibles.

              • @tunzafun001:

                try and make a LiFePO4 pack go up in flames…but cant!

                lifepo4 diff chemistry to what's used in ebikes etc so not quite sure what your point is

                • @0jay: More bikes are using LiFePo4 now. It's a bit heavier, but on the scale of the whole bike, it isn't much.

                  • @tunzafun001: clearly the fires that're so widely regarded as lithium fires're not lifepo4 devices

            @tunzafun001: Manufacturing faults don't exist?

            • @tenpercent: yeah, but the only solution to that is not use anything electrical at all..nor petrol…basically anything energy related…padded cell territory.

              But yeah, I guess 1/3 rd could be low grade / low cost quality control. DYOR.

              I just bought an AliExpress car jump starter. Opened it up and resoldered it all..it was $hite

                  Aldi stuff is normally pretty good. But I would 100% be checking inside to see everything is nicely connected and insulated.

                    @tunzafun001: We also used to have stuff made in Western countries or more advanced eastern countries where morals and standards were higher.

                      @tenpercent: We also used to have Western countries who had CEOs who didn’t prioritize profit, but they did. Look up Boeing with the 737 Max. VW with the Dieselgate. Morals and standards aren’t exclusive to some countries.

                      @tenpercent: Morals and standards don't provide craftmanship and engineering. Quality assurance does that and some non western or advanced eastern countries do it very well indeed. Comments like your are just zenophobic and tend to be made to incite response…….like this.

                    Pretty stupid statement to make. Not everyone is an electrical engineer. You want customers to open up and check every electrical/electronic item they buy? I will let my Granny know to not be Kardashian and to check if everything is nicely connected and insulated, next time she buys anything electrical.

                    • @dealhunter52: Not quite. What I'm saying is if you want a cheap ebike and dont want to burn your house down, then learn how the thing works and check it over. Im not an electrical engineer. I learnt this stuff myself from books. These days everything is on youtube. Couldn't be easier.

                      Alternatively, you could pay more and hope the quality is better, or pay someone to check it out.

            • @tenpercent: Not for Aldi, they're good, different.

    • +1

      You can't directly know the quality of the cells and BMS just by looking at a bike like this, but there's a couple of other factors that make it clear that this is a bottom of the barrel type ebike. The way the battery is not incorporated into the frame indicates that they've just taken a cheap mountain bike and tacked on electrical components.

      They say it's a steel frame, but steel frame bikes are generally quite expensive and they do not have wide flaring tubes like this bike. It looks like an aluminium frame. If it is steel it will be really heavy.

      Finally the mechanical disk brakes are not really suitable for an ebike IMO particularly for larger/heavier people. The cables will stretch quickly and become dangerous if not carefully maintained. An ebike can weigh double an equivalent accoustic bike, plus the rider's weight, and the off the shelf brake components are not designed for that. And guess what, the kind of people who want to buy the cheapest possible ebike probably do not use it very often and probably do not maintain it very carefully, and probably are not the most skilled and confident riders. So as a result we have a lot of people riding around on ebikes that can go a lot faster than they would be able to ride without the electric assist, and are heavier, that they cannot stop very well.

      So, again not sure on whether it will catch fire, but it may kill you in other ways.

    • Bikes bought locally and from reputable brands are unlikely to cause fires. You should still exercise general precautions like tunzafun's comment

      The ones that cause fires are when people modify them (often illegally) or the outright motorbikes (illegal bikes with over 250W of output power) that have been cheaply imported from overseas. N.B. These are illegal and non-compliant motorbikes, NOT e-bikes.

    • +1

      With an Aldi bike, it's likely they have done all the correct certification.

      If I were to guess, the bulk of the fires are from cheap non-compliant imports as the fire fighters seem to suggests in this article : https://www.abc.net.au/news/2025-02-21/battery-fires-statist…

    • I know nothing about ebikes but have seen the footage. It's so scary the heavy foggy smoke filling the entire apartment in a blink of an eye.

    • what's a

      rash of lithium battery fires lately.

      You probably hear just about every single one.
      Apparently (according to the bot) there's over 1m ebikes in oz (based on 200,000 sales in 2020). So it's not really a problem. an old firery mate years ago told me the biggest issue are (profanity) plugging them into powerboards and overloading them. They catch fire, the battery catches fire and you're f'd

      But I'd be wary of cheap ebikes because they're crap. The batteries aren't high quality (like buying cheap rechargeable batteres from AliExpress) and that's tje most expensive part to replace. Also 36v/250w hub is a bit gutless.

      • the biggest issue are (profanity) plugging them into powerboards and overloading them. They catch fire, the battery catches fire and you're f'd

        Sounds like an unnecessary hazard that could be engineered out. If it is common knowledge that this is how lithium battery fires tend to occur then manufacturers have some answering for.

        • most batteries don't like fires. Not a lot manufacturers can do to stop their batteries being in a fire.

          • @M00Cow: Someone should tell them about flame retardants.
            Or they could design their charger to not accept a charge from a powerboard.

            • @tenpercent: Batteries don't burn, the chemicals inside do, and they're self catalysing, so flame retardants (which are used on almost all casings) will do bugger all to mass stored energy.
              It's akin to buying a 'blast shield' and expecting to withstand a direct tank impact.
              Sometimes the stored energy overwhelms even the best safeguards.

              Also, most lithium fires don't end up burning down the house, most are LiPo based and become smokeshows more than flamethrowers.
              You just hear about every flamethrower incident, to encourage more awareness and care in the community.

              Or they could design their charger to not accept a charge from a powerboard.

              How are you thinking?
              Powerboards are literally just duplicating the wall socket; how could it know?

  • think it's this one (the battery is not in the frame like the one you've linked)

  • Steel frame might make it a bit heavy if looking to transport it I'd bet. Not an issue if only using it locally, seems a decent price.

  • Keep in mind that there is a possibility that eBikes will be banned on public transport on the upcoming regulations review. Have your say on it here https://engage.vic.gov.au/public-transport-regulations

    • in Victoria…

    • It is proposed that:
      • E-scooters and e-bikes no longer be allowed on trains and coaches
      • Only foldable e-scooters and e-bikes be allowed on trams and PTV buses

      • Other battery-powered transport devices, like e-unicycles or e-skateboards, be banned on trains, trams, buses, and coaches

      I hope this doesn't come to pass.

    After playing around with an Ebike over the last 12 months.

    250w @ 36v is great if you live on the flat. Not great on hills.

    7.8Ah is 3 cells x 10 lots. 3 cells isn't enough to cover large current draws and will fail early on hills, and heavy reliance on flats. You want 10Ah minimum (4 cells).

    I took a 36v 250w hub and put in a 48v controller ($20 on Temu) and battery. Light years better (I live on a hill). The Bafang 250w hub happily takes the 500w+

    I think Aldi has missed the mark, unless your commute is dead flat and you like active pedalling and just want a little assistance..which would draw 140 watts and the battery would happily take that for a long time.

    But..it has a 60 day trial. More bikes and less cars is good for everyone..

    ALDI's electric bikes tend to sell poorly. My local store still has stock of the foldable bike they started selling four months ago. Even at $399 they can't convince someone to buy it.

    There is also no mention how heavy this bike is.

  • It is not mountain bike. It is a commute road bike at best. Nice to ride on a flat road. Cheap and may last a year or two.

  • Available in the following frame sizes: 1 size fits all.

    "Coupled with a 36V 7.8 Ah lithium battery, you can enjoy extended rides with consistent power…" you might squeeze 60km range if lucky.

    "Shimano 7-speed gears provide smooth, reliable shifting,.." good luck with that derailleur.

    "Mechanical 160mm rotor disc brakes" - surprised it hasn't got V-brakes ?

    Even the Chinese ride better bikes than this !

    BIL comments who works in a Trek bike shop. This is landfill quality. 27.5" wheels are dated, 29" wheels are the status quo. A 50W motor will have severe limitations. Expect a range of 10-15kms, any uphill travel will significantly reduce it and may likely overheat the motor quickly. 99 bikes often has good sales where you can pick up something with a 400W motor for $1200 with local support and servicing.

      A 50W motor will have severe limitations.

      Anyone who works at a bike shop should know 50W is a misprint.

    • The person buying this bike doesn't care that the wheels are 27.5" rather than 29". There's still plenty of serious mountain bike riders who prefer 27.5.

      The bike's a piece of crap obviously but the wheel size isn't the reason

    • Expect a range of 10-15kms, any uphill travel will significantly reduce it and may likely overheat the motor quickly.

      You can always use human power and, you know, pedal up the hill…

      27.5 vs 29 wheel size is just personal preference - I can't see how it would make any difference to a potential buyer looking for a bike at this price point.

    All of the parts on it are total junk. If it lasts a year of semi regular use I will mail you a cerificate.
