    Can anyone compare these two bikes.

    That's horrible news about Bafang not the way we want the industry to go especially as we are trying to be more environmentally friendly and use products for longer. I'm not going to claim to be an expert on Bosch motors but have seen many forum postings where Bosch owners have complained about...

    Can anyone compare these two bikes.

    I don't think its hate its just mid-drive is overly complicated and delivers its power through the drivetrain making it a higher performance but more troublesome and higher cost ebike solution. I went into a bike shop today to have a nose, not a ebike to be seen for less than £3k and none that...

    20 inch 48v 250w front wheel/ kit- seeking recommendations

    I had a look at your other items like this ebike at £465. I'm impressed with how discrete the ebike components are on it. On face value it looks like a standard carrera folding bike that used to sell at around £320. It's now been replaced by a disc brake version with a completely different frame...

    magicmary cracking up

    Well I could be wrong but I was thinking after the tyre was new, and less flexible and supple and then being flexed more because of the lower pressure. A bit like side walls perishing with time with the constant deflection of use.

    magicmary cracking up

    It's not a tubeless thing then. Typically when people run tyres tubeless at lower pressures the tread can get more of a beating as it forms more aggressive angles around the ground surface and more likely to crack. So more grip but shorter tyre lifespan.

    Rear hub motor or front wheel motor

    The best regen motors seem to be geared hubs weirdly but you have to disable the freewheel type clutch plate. I think without the freewheel mechanism they become even more grim cycling them without power to the point where I think you have to operate a trickle current type situation to restore...

    2 Swytch conversions and a kit from Amazon

    It's the nature of Swytch's business model. Their kits have a full retail price of £1000 and half that for pre-orders but if a Chinese supplier configured a kit like that with a small geared hub motor and a tiny capacity battery you might be able to buy that kit for £250-300 retail price. I...

    Rear hub motor or front wheel motor

    I think losing grip on the front has been massively over-stated by many but I'm sure a light rider going up a steep hill with a powerful front hub motor may well lose grip especially on surfaces with poor grip for sure but for legal wattage ebikes I personally don't think its an issue. On some...

    First Build - What's your recommendation?

    I must admit I'm a huge hub motor fan and think they are by far the best for general cycling especially some distances but I have a nice retro Saracen downhill mountain bike and it has to be mid-drive I feel to maximise the enjoyment off-road so I'm holding out until I can get a mid-drive motor...

    Help. Ebike conversion

    The images I see for the torque arm don't show the axle fitted but show the torque arm being designed to tightly hold the axle in the axle hole of the torque arm. However on the dropout of the Subway on the driveside there are two holes close to where the metal will be filed out in order to...

    Help. Ebike conversion

    There is nothing illegal about a direct drive hub motor configured with a controller giving out 250W nominal and only assisting up to 15.5mph. In fact many commercial mid-drive motors like Bosch peak at far higher watts, over 700W. It has to be large due to the simple design internally without...

    Help. Ebike conversion

    There is a lot of information on the Grin site regarding torque arms and some handy diagrams. They don't mention filing the dropouts on the page. https://ebikes.ca/product-info/grin-products/torque-arms.html I'm sort of between Grin and Nealh regarding this but I have to bow my head to...

    Help. Ebike conversion

    Those look like normal dropouts to me. Remembering that aluminium is softer material I think you will need at least one possibly two of the torque arms which will be steel and far stronger. There is a video here with another Carrera model with possibly similar rear dropouts on the frame. I only...

    Help. Ebike conversion

    Going to need more information ideally. Halfords have been doing the Carrera Subway model for at least 15 years and have had various different models plus they have changed manufacturers many times. Also which kit is it. It may simply be that you need a torque arm kit to secure the hub motor...

    Wisper Bike.

    Gorgeous colour on that frame. Interesting spec with XC front forks and off-road style tyres but a step thru design and lots of carrying capacity. I guess its a SUV of ebikes rather than a 4x4 of ebikes. Great for cycling in the countryside on rough roads etc.

    Help! Cube Supreme Pro 500

    Many hub motor kits include a throttle which is perfectly legal as long as it only operates while you pedal. This can give smooth control of power to get up hills etc which many older cyclists prefer over torque based assistance which is preferred over stepped power delivery of some hub motors...

    Help! Cube Supreme Pro 500

    The Nexus 7 is a 9 speed mechanism with 2 gears mapped out so you can't use them and sadly I think one of those 2 gears is the 1:1 direct drive gear. I think Shimano wanted a nice clean 7 gears that stepped nicely and they did that by mapping out two gears. The lack of 1:1 gearing and the more...

    Help! Cube Supreme Pro 500

    Nexus 8 hub gears are great but they are fairly complicated with a lot of internal parts as has the Bosch motor system. Typically from what I've read in forums the Nexus 8 might last between 8,000 and 20,000 miles on a standard bike although early failures also happen. However when you combine...

    Viking harrier handlebars

    Best of luck finding the right parking. Sometimes there are park and rides you can use but you haven't mentioned the area. Here in Yeovil there aren't a lot of resident parking permit areas I think its mainly around the hospital so you are forced to use their extremely expensive parking or the...

    Viking harrier handlebars

    Maybe they bought it with the dead battery then replaced the battery and realised she didn't like it so then sold it on. I guess maybe she found the assistance lacking too due to the 24V battery and motor. I still feel it could be a competent ebike for you with a slight modification to the...
