    Help! Advice on a readybuilt or bike to convert for a heavy person (20 stone)?

    Decathlon have low weight limits, 100kg on most models and that is total load. They also have had quite a few recalls for frame failures. I guess it depends on model but with many brands offering a full 160kg total load capacity those would be better options in my opinion.

    Help!! First ebike!!

    How do you know that if such bikes have sold in huge quantities compared to other brands. If Carrera have sold 100,000-200,000 of ebikes fitted with Suntour ebike systems and another brand has only sold 10,000 unless you know the actual failure rate it is unfair to criticise them. A high end...

    Are converted bikes legal?

    I don't think the law is particularly good in this instance and most of the companies providing ebike systems operate outside it. I think the EU law states continous power should be 250W or less but many of the motors will happily work at 400W without problems on mid-drive ebikes in fact the...

    ELECTRIC CARRERA VENGEANCE PROBLEM

    So what didn't you replace between the donor bike and your bike. I think the torque sensor is a common area of failure plus cables can get damaged. I would search these forums and youtube by Carrera suntour ebike as many of the carrera ebike models use the same suntour motor system and have...

    Help!! First ebike!!

    The Carrera Subway ebike at Halfords is very good and in your price range. It has a torque based sensor so delivers more power the harder you work in a similar way to mid-drive ebikes but is still hub motor based. It uses a Suntour designed ebike motor system which does have some history of...

    Front or rear hub motor?

    Kenda are a huge manufacturer who also sell under their own brand. Lots of bike brand tyres are made by Kenda. I don't think they are as big as CST though and own brands like Maxxis and make tyres for brands like WTB. There is also PT Hung-A who are a big player but nowhere near the size of CST...

    Front or rear hub motor?

    Also at the cost of grip and uneven tyre wear. Action cameras that mirror the image to your phone are a good way of finding the right deflection for your weight. You can place them on the ground facing the tyre closely then sit on the bike viewing your mobile and start testing each tyre...

    Front or rear hub motor?

    Front hubs are better in lots of circumstances but basically they make more sense the heavier the load to help apply more downward force. The weight distribution of bikes is something like 60:40 or 70:30 to the back depending on how the rider positions himself. Front hub motors are simpler...

    How much current do you need to inject into a direct drive motor to simulate freewheeling?

    That's a useful comparison. Where would you put lets say a 14-15kg un-assisted mountain bike in there. I'm a heavy rider myself and don't feel soo much difference between bike weights as they become less significant because of my greater weight. When you are 120kg, 3kg difference on the bike...

    How much current do you need to inject into a direct drive motor to simulate freewheeling?

    That first paragraph sounds right. The second paragraph sort of sounds like you are taking the bike weight into account as well so almost like you are trying to calculate out the greater weight of the ebike as well as the freewheeling resistance if so that sounds right too at an extra 50W...

    How much current do you need to inject into a direct drive motor to simulate freewheeling?

    Just curious on the views on this. I think I read somewhere around 6-10W power depending on hub motor but I can't seem to see that information now. I wonder if there is some formula for working this out. I think its Grin technology who state that a combination of injecting such current plus...

    China Bashing

    Many of the best Chinese factories are Taiwanese owned, they have great engineering standards and have done brilliantly in electronics and bicycles. The culture of the Taiwanese is completely different to mainland Chinese. I've been surprised how different they are, the Taiwanese are a great...

    Help! Where have all the e-bikes gone?!? (Looking for e-bikes in stock...)

    Remember ebikes aren't like normal bikes, the battery pack has about a minimum of 500 charges at full capacity and then capacity starts dropping making the bike less usable. People often sell their ebikes with end of life battery packs for quite high prices. Ebikes make more sense new than...

    China Bashing

    Lots of factories in the UK are very efficient, Nissan in Sunderland is praised as being one of the best car factories in the world for productivity. I've seen Chinese factories reported with suicide nets to stop workers jumping out from the top of buildings and killing themselves. Other...

    Help! Where have all the e-bikes gone?!? (Looking for e-bikes in stock...)

    There's one here in stock at £569.95 but its a fairly basic bike but does fit some of your criteria. It's only a 24V battery but then it's 20" wheels so its more lower geared than larger bikes which is easier for the motor hub. It will probably sell out very soon, the other two colours are...

    China Bashing

    The way its going, we are leaving the eu with probably 40 years of extreme debt to pay back and we now have all the covid 19 costs and leaving the EU will not be an instant cure we will have to find out feet outside the EU, the economy will likely tank, people will be much poorer and the £ will...

    Heavy Newbie Help.....

    I think for tyres I would go with the maximum size tyres that the bike will take and choose heavy thick tyres with thick sidewalls not tyres that sell on lightness and speed. A tyre normally states half the pressure it will fail at as its maximum pressure, i.e. 60PSI would be around 120PSI where...

    Carrera Crossfuse (Active Line Plus) struggling with hills

    I know it varies a lot on mid-drive motors and in fact when you look at the internals of mid-drive motors the designs are often very different. The newer Bosch models are much better than the older ones. With regard motor hubs its like the direct drive hubs always have a lot of drag and the...

    voodoo or cube or scott

    I realise that in fact I put the link above in about Cube making ebikes in Bangladesh who have or had favoured trading status with the EU. I think ebikes exported from Bangladesh and Cambodia have to have at least 30% content by value manufactured in those countries to avoid the Chinese ebike...

    Carrera Crossfuse (Active Line Plus) struggling with hills

    I guess my real point if I explained it better was the benefit of the torque sensors in both some motor-hubs and mid-drive units that match your power more where as a basic cadence sensor on budget ebikes is more of a on/off switch so you only have 4 or 5 power levels unless you also have a...
