Also bear in mind how aluminium fails. It fatigues over time. I think the certification is done to give a realistic lifespan of 7-10 years of reasonable use but if you overload the frame or ride very frequently this will reduce. Frames don't fail immediately. 10% over stated load is not a huge...

New legislation that makes it easier for people to get onto ebikes would surely be beneficial. We left the EU with horrific debts and have now got the pandemic costs on top. We are paying something like £83 billion a year in interest which is approaching £3k in interest for every working person...

I feel its like comparing a Landrover, McLaren sports car and Toyota Corolla. Each have their purposes and to use one compared to the other needs a more defined use. I like to go off-road but very light off-road which a gravel bike could do mainly and I really don't need sophisticated suspension...

If you are spending £30 I would get something like this; https://www.amazon.co.uk/XOSS-Computer-Speedometer-Waterproof-Bluetooth/dp/B083XZ3584 It's a GPS cycle computer with lots of additional functionality and needs no wheel sensor and can be moved easily to different bikes. Yes you will...

I think on a direct drive motor with regen you could use the motor and your own power for the hills, use your own power exclusively on the flats and regen down the hills to give yourself a huge range possibly 100s of miles out of a large capacity battery. If the bike is configured with a...

Yes from China and took 3 weeks approx however there was no tracking information and when I looked at the parcel it said something about coming from a UK address on a trading estate somewhere. Maybe bulk shipped from China with other orders and then individually sent from within the UK. I'm a...

I've been impressed with the battery as far as I can see so far. I'm fairly sure its the genuine capacity as stated which is 720Wh despite the lowish price. The previous ebike batteries I bought were over 2 years ago and I bought two hailong based batteries of 624Wh capacity that were £150 each...

As a very rough guide if you share the Watt hours by ten of the battery that gives you a the range in kilometres for the average ebike with average effort by the rider. So if you had a 36V battery with 10Ah that would be 360Wh so the range w ould be about 36 kilometres or somewhere around 22...

Interesting reading, I would of thought that type of bike was the type of relaxed bicycle where you would not want to have such a surge of power. It might make sense on a speed optimised road bike but surely not for that type of bike. Sounds like a bike that really needs a throttle control. So...

Does this happen on all three power settings? Have you tried cleaning around the cadence sensor and perhaps re-positioning it if its been knocked out of position? Looks like it has a metal crank cover, its possible the metal of that crank cover is interfering with the crank sensor if the...

Ok it looks to have taken about 7-8 hours to charge to green and that is a 2A charger with a 15A battery so I think that is hopeful for capacity with I guess a minimum charge in the battery when shipped. I'm going to let it continue charging for about 3 hours to balance the cells before...

I'm sure it doesn't effect your newer Tern but some of the failures were quite funny. There was a russian forum where the father had given a Tern to his son with the idea that as his son grew he could just alter the height of the seat and handlebars etc so wouldn't have to buy him another bike...

I'm sure that is a fair point but the price of such chainrings is all over the place. I bought one at £2.99 and next week the same chainring is £14.99. It's like they price them low just to get a few sales and decent reviews and then completely change the price. I'm using one on a Saracen Pylon...

I didn't mention it before but had a bit of buyers remorse with regard the battery pack I bought. I pretty much went looking for a battery pack as soon as the kit arrived and ended up buying the 48V 15Ah version of this battery which at the time was about £80 so with VAT about £97 and about £4-5...

I'm really surprised I would of thought that was standard for mid-drive ebikes because they almost always have a 1x drivetrain so no downside to fitting a narrow wide chainring. One of the huge benefits of going to a 1x drivetrain on standard bikes is narrow wide chainring and better chain...

I don't think the original groupset is bad its used on many standard bikes without issues. If you fit it to a ebike with a mid-drive motor the story is different that motor adds hugely to the riders own power and the story is very different. On a hub motor ebike because the motor is independent...

Perfect bike for any ebike conversion really, strong aluminium mountain bike frame with chromoly steel forks and strong 26 or 27.5" wheels depending on age of model. If it was a Carrera Subway 8 (Nexus 8 rear hub) you couldn't do a rear hub conversion and you shouldn't do a mid-drive conversion...

What is the bike you are converting to an ebike and does it have decent low gearing? I think Mr average produces about 50Nm of torque over an extended period but a weaker rider could be around 30Nm and then you have the gear ratios on the bike and the different motors. I think a direct drive hub...

It's important to understand the vast majority of ebikes in the world are hub based and that is simply because hub based ebikes are much cheaper and cheaper typically means accessible to more people. When I was looking around various sites it had something like over 95% of ebikes are hub based...

Some of the Bromptons are just 3 gears i.e. just the SA 3 speed hub but others have the 2 speed derailleur system which gives them a wide range of gears similar to the Nexus 7 or Nexus 8. It's how Brompton got around the much reduced reliability of the Nexus 7 and 8 for long term use. Some may...
