No one can buy a two piece torque arm and use a secure fixing for it, a hose clamp is not the answer.

Six years ago CS from them was poor so if they are still in business, tread carefully.

Yose is likely still one of the best options, as to the cells used a lot of China brand cells are now being used due to the shortage of top named brand ones and the rising cost of them. Not all China cells are bad as there are quite a few good ones out there. The thing with a battery where the...

One will have to be very careful on the drive side, there is little material to play with. As one mills out deeper then the likely hood of a stress fracture occurring increases, the two tapped holes marked (one the gear hanger) will end up with less material between them and the d/o seat cut...

The D/D hubs axle are 14mm deep, I have yet to find a d/o this deep unless it is horizontal one used for hubs geared bikes or fixed gear bikes which the design is for whee position/chain tensioning. The grin site diagrams would suggest the drop out is already some 15 or 16mm in depth which one...

At all costs avoid securing a torque arm using the hose clip method, a secure fixing via a threaded bolt hole or a through hole with a snug bolt and nut fixing. Both sides of the d/o'd need to be milled out equally so the axle sits horizontal, don't rush the job. Better to take a little at a...

Though filing isn't mentioned the Grin page diagrams shows the axle filly in the d/o with the flats of the axle well covered by the d/o, ali can and will over time spread/wear if no torque arm/s are used to counter the rotation. No standard bike frame will have drops outs that deep whereby no...

These brakes are 4 pot e brakes. I lied they aren't £69 they are a penny short of £70.

Is that because they don't use hall sensing and are unsensored and the sole hall is for internal speed magnet ?

For £69 on can buy a set of complete 4 piston hydraulic brakes.

Next week I shall find time to open the hub and double check the speed magnets. Then I shall retro fit a lcd3 for testing when towing to see if the same issue exists. There is something a miss somewhere as a couple of time I've seen the erratic speeds before towing started in earnest, so feel...

No I have real voltage data read out and voltage sag is minimal < 0.04 - 0.05v, I'm using quality 20a cells or a hi rate discharge lipo . The performance from the batteries is good actually on a 11 mile route, I'm seeing start cell V's of 4.15 -4.18v and end V's at 3.88v so at least 22 miles...

I have seen that the guys on ES already on it and trying diy the system to get into the Canbus to make changes. Batteries might be another thing ,time will tell. And looks like SW is correct all motors post 2021 are Canbus. Bafang M620/G510 (and all other Bafang motors) now on CAN-BUS (2021+)...

Use a dremel tool with course milling bit and one should be able to take out about3 mm from both sides (or enough so the axle flat sits wholly within the d/o) , just be careful and match the axle seat profile for a snug fit. For torque arms make you own one piece arms out of steel 2 - 3mm...

The 1000w hubs usually have a 14 x 10 axle so getting the 14mm depth to sit in a std 9mm qr d/o doesn't work hence the axle simply rolls out. The difference is approx.2.5mm needs to be filed out of the d/o, fi possible. The brake side isn't an issue it's always the hanger/gear side. Ideally one...

They have large arrows on them, makes no difference. We have to accept poor CS from the couriers or none at all, it is often why they don't get many stars on a review. Problem is we only see the final act of the process at the door and not all the stuff that goes on in between. I have had large...

Yep, as the vendor one has to cover all angles to reduce the impact of poor handling by third parties.

Samsung cells is a sign they are li-on, I haven't seen Sam pouch cells. Likely 10S6P of Sam 26f cells.

That's couriers for you, they don't really give a monkey's gonads.

No it is normal, those DD hubs have no freewheel, they are a bugger without power. To recommend a controller kit we need to know the continuous current the battery can sustain and not the peak current.
