Electric Bike Deals & Offers

Is that including air drag? Without calculating it you have a massive over- estimate of power gained, as your model assumes the regen braking will be so strong that you are going 5mph downhill (where air resistance is a small factor), but in mountain biking you would be going alot faster, probably averaging at least 15mph (where air resistance is a huge factor)

I did the maths and you're right, like assuming a vertical hill 1km high and a 100kg bike + rider combo, reasonable efficiency, you spend about 400Wh going up but gain 130Wh going down with regen braking on. Not bad at all. The trick is you need a hub gear motor and extra power circuitry for regen braking so the resulting bike will be heavier, not enough to make it not worthwhile but a heavier bike with more unsprung mass will be less pleasant to ride.

Regenerative braking or some kind of dynamo would probably add a decent amount of energy for a mountain bike being used up and down hills. You'd also lose more energy going up steep hills so the 108 mile range would be reduced.

To be fair, for off-road riding that's still a respectable distance. Or, to put it another way, you'd be a sweaty mess after that distance offroad with a regular bike :-)

If you are lightweight, fit, on the flat, no or wind behind you, tyres at 70 psi, on the lowest assist setting. Otherwise expect about 40 to 70 miles

Thanks. Kind of helps. Made me realise I need a diet (y)

Was just about to answer lol. Like the man said it's around 11stone.

70kg works out to be just a little over 11 stone, or 154 ish pounds, hope this helps.

70kg? What that in real money?

K trap a to B. Absolute tune

You realise Plato quoted Socrates saying much the same about himself, your name isn't Sophia by any chance? Even in your screenshot states "The weights listed are for general reference only; check the documentation included with your bike for specific weight limits". Must be beyond me to recognise the industrial guidelines all e-bikes much adhere to being quoted in their generic manual for the other product range of the Xduro that also states to look at the documentation supplied for the specific bike Community forums are about discussing what is correct - ego is about dealing with who is right and wrong and hinders people getting to what is correct. In the main I am reflecting the parts that you are excluding from you bias - when not going off piste.. That is your opinion - I think they have configured as their entry level mid motored bike with some features that I personally like on that frame e.g. the motor guard. The reviewer you posted up also stated he liked the frame a lot Everything else you are projecting I have said isn't the case but it would require you listening beyond yourself. Your recommendation as an alternative better and cheaper bike, according to its specifications, has a Suntour XCT, Mechanical brakes, Pro wheel chain set whilst not being mid motored and I have already flogged to death your advise that I consider dangerous. To you I would Bonzo as you can't hear what I am saying. Anyway I am out of here as you are going to continue talking to yourself no matter what.

Again you don't seem to understand much. Rider weight of 120kg is different to total permitted weight of 120kg, one is the rider weight on it's own without luggage or the bike weight itself and the total permitted weight is everything. How can you not understand anything so basic as that. You seem to be pre-occupied by your own ridiculous and incorrect opinions. Anyway here is the detail from their manual. I hope we can finish with your absolute nonsense now of the Haibike being a stronger bike. It is significantly weaker as you would expect from that frame and geometry add to that a more complicated and less reliable motor type. While Haibike may have light duty off road bike on their site it isn't being repeated on all websites selling the bike it is sold as a simple e-mountain bike. They have also configured it to look like a serious off road bike despite its many weaknesses. Your opinions are so utterly biased and ridiculous it is farcical. You are clearly wrong here, you have pursued this point but failed at every opportunity. You also lack any sort of level of politeness and just come across as some offensive keyboard warrior. https://www.4qte.com/pdf/Haibike/Haibike eBike Owner's Manual 2014.pdf

Sduro Hardseven is advertised by Haibike themselves as a light off road bike, here is the is a screenshot from their workbook: I copied the reviewer - albeit again you have cut off for the urban rider and with the warranty wear and tear would not concern him - much like you saw what you chose to see in the review rather than taking the full pro's and con's. EN15194 is about requirements for ebikes - a none ebike has no requirement to conform to this requirement in the context of retro fitting. This is where I think your advise suggesting that most bikes can be retro fitted is a dangerous one in an open forum. As pointed to the comparison between the non ebike and ebike from Haibike most laymen should be able to see the ebike is strengthened in a number of area's where the load differs between that of a human rider to a motor driven that goes beyond the weight to also the forces applied. I also made the point that the Haibike has from the ground up designed, specified and had a frame built for a mid drive motor. The Carrera (which is like comparing apples to oranges in relation to this mid drive Haibike) has taken a standard design and strengthened those key points required. Feel free to take a set of digital callipers and check the differences between the e variant and none e variant of their same bike in your local Halfords. As to you made up 110Kg for the Haibike and the Carrera being some 30kg more this is the spec of the Carrera on the left and the Haibike on the right: If you would like to look at the mountain bike magazines and awards you will see Haibike are up there and considered at the cutting edge and often first to market in pushing the envelope especially with their Yamaha and Bosch solutions. Of course if you want beyond entry level then you need to move your budget further north. If you were to move the analogy with cars then the Carrera would be closer to a Dacia - reliable, clunky, cheap, older tech but really nothing to get excited about. I answered all this morning when you posted which was deleted by the moderators as content was deemed not suitable and on that note I give in trying to keep you on track to the relevance of the Haibike in this offering or adding my tuppence where I can. So long

Again the bike is listed as a electric mountain bike which implies normal mountain bike use. You are describing light off road use which many bikes are capable of. As you have mentioned the Bosch motor version offers shift sensing which will reduce wear on the chain, sprockets and derailleur and that review stated even with that feature without even going off road those components had to be replaced 3 times in 1 year for a higher mileage cyclist. The Yamaha doesn't have that system so seems likely such wear will be higher. Crank motors are high torque which is ideal for real off road use but pairing them with lower end components effectively ruins that capability or means a product that is very high maintenance and give the cogs and chain a huge workout. Pairing such a motor with such a low end bike with lower end drivetrain components is a poor match. You may criticise hub motors for their lack of torque for off road use but some of them work very well over the long term even if they never quite achieve the same performance off road as the higher end haibikes. This haibike model looks like it would be high risk to take off road with some sort of failure likely either in the motor or drivetrain or possibly an issue with the basic forks. Going back to the retro fitting of hub motors on conventional frames. All these bikes are certified and tested and then rated for load capacity and other factors. The Haibikes have a lower weight rating than many conventional mountain bike frames that have been fitted with hub motors. All these bikes have to comply with EN14766 and EN15194. The fact is the certification often dictates the final load capacity of a bike. Despite the huge number of Carrera bikes sold in the UK, frame issues are not common. They often feature reinforcing not seen on their competitors. Like the Haibike frames they are probably manufactured at the huge fuji-ta facility in China but that facility makes light duty frames (often destined for it's own domestic market) and much stronger designs for the US and Europe, basically what the customer pays for. There are a lot of reports of Haibike issues for what is a niche product in the UK. Again no one is saying that a mid mount crank motor isn't the ideal for a mountain e-bike it's just such bikes do not cost £1,500. With a £1,500 price tag its probably hard for many to see this bike as entry level but it is for this type of product with this motor type and frame configuration.

This is link to the ebike I returned,same make as op I think, absolute pile.of (poo) http://www.argos.co.uk/product/8019378

HUKD voters strike again! I posted a basic electric bike and it's well over 400 degrees and rising. I then posted this much better electric bike with gears, folding frame and better design for £50 more and it's gone cold. Can anyone explain? Anyone?

Thank you. Had a look around and this appears to be a good deal. I have bought one. Collect later. The gears and the ability to fold are worth and extra £50 over the other non-folding version which has reached around 400 heat. Thanks again.

Hot vote from me, as it IS good value. No need to worry about cold votes, this link may not have been clicked-thru by many from the other thread. This is a great find for those of us looking for a cheap elec' bike - bonus that it's folding too 👌. Best wishes

Very low end drivetrain and no handlebar height adjustment limits the suitability for various height riders. It's an ok price but not great in my opinion. Not sure it deserves to go cold though.

Nah, that's *******. Any half decent mechanic will check the tyre and tube is seated correctly before inflating it, especially if it's new from the factory. It'll be on a PDI-checklist they have to fill in.

never liked the apollo range in halfords - they always seemed too cheap looking whenever i have gone for a closer look ( maybe some are better than others like the carerra range - seen some good ones & some that boggled the mind as to why they bothered with it lol.) the apollos always seemed to have that supermarket type of feel to em to me ( but on saying that, my 1st bike was a bike from ASDA over 20 years ago & i still have it & its still going strong even though i have never treat it with much kindness.

It was actually my flatmate at the time who paid for the goop add on as we went halves on the bike, as we were sharing it, but he picked it up from the store and he's incredibly gullible and he bought their sales pitch hook, line and sinker at the store. When he came back and told me what he'd paid £12 for I laughed at him because it seemed absolutely pointless to me. Although, as a retailer, you have to take responsibility for your products whether it was you directly who messed up or it was the supplier who messed up, it's up to you to make sure they are of suitable quality because you're the contact with the customer, meaning the customer complains to you and you complain to the supplier. As far as we, the End User, are concerned, it should be Halfords at blame because they are choosing to use that supplier, the bike was an Apollo range bike too which is Halford's own brand so it's not like that type of bike would be sold by other retailers. (The gears and brakes were bloody awful on it too but for all the bad stuff I say about it, it was no race horse or pure bred, it was a donkey, but it was a reliable, stubborn, and tough donkey. I rode the hell out of it in all weathers and conditions and it's still able to take more punishment, so it's not all bad.)

did your new bike have Presta or Schrader valved innertubes ??? if presta then its probable they were at fault indeed as not many of the bikes they sell come with suitable tubes as standard so you have to buy a slime tube or something like a continental tube & have it slimed ( or other brand that has removablable valve cores ) BUT if they were schrader valves ( car valve type ) then when you paid for the slime in the tyres addon, the store will not have removed the tyres or replaced the innertubes at all, instead they will have just removed the valve & sloshed in a suitable amount of goop from a huge drum of slime they have, refitted the valve core & reinflated the tube - thus transforming your boggo innertube that was already fitted ( badly ) by the factory into a slimed tube so again may not be the stores fault fully here. ( not all stores will operate this way but thats how my nearest 3 seem to operate with regards the slime stuff - next time ur in ur local see if there is a honking great barrel of green goop behind the counter, if so then thats the punture goop you paid for a squirt or 2 of :) )

do you work there

Thanks, hopefully wont have to change a tyre but that's reassuring.

Don't know for sure about this one as we're still awaiting delivery, but my experience from other electric bikes, it's simply a case of unscrewing the hub nuts (like a regular bike wheel), and carefully sliding the wheel out of the disc brakes and frame. Some electric bike makers then allow the power cable to be pulled apart (usually under waterproofed heat-shrink), freeing the wheel for the tyre change. Some have the power cable attached to the wheel, so the tyre change has to be done very carefully next to the bike as not to damage the cable. It's shouldn't be too difficult.

fingers crossed is arrives quicker than the 4th of sept, checked forum posts from people in france italy etc and they seemed to be getting theirs within 5 weeks. Surprised they m365 is poor in wet conditions, almost chose that instead of this bike as my last-mile solution! Does anyone know how easy it is to source / change tyre, imagine it'll be a faff especially the back wheel if you have the motor to deal with, seen halfords do 14" tires but unsure if compatible.

Just rode the Xiaomi M365 in the wet for the first time... total disaster... No grip while cornering. Really need this Fiido to arrive quicker.

I just wouldn't touch the access point, and let them deliver to your home as normal. GB have said I should now allow until 4th September.

Now out of stock but my 'expire' button has disappeared!

cool ok - might have to get one then thansk for the update

It has a conventional frame so a trailer should fit and plenty of people use trailers on ebikes. Within reason top assist speed should stay the same.

this bike looks interesting does anyone know if a bike trailer would fit to this and how it would perform with a trailer attached

Someone (Mod? Ed?) has unexpired this and removed the expire button! Odd.
