Re: Replacement battery for e-bike (different voltage and Amp hours), will it work?

What Motor kit is it? Some kits can be reprogrammed.

I have a Tongscheng TSDZ2 custom kit. It has the benefit of being a 48V kit but I run a 52V battery to aid range and cooler running by using higher voltage not Anps. I can alter battery voltage to suit what battery I decide to use

Re: Gear changing strategy; how do you use a triple?

I have a triple setup on my Tripster ATR its Di2 gearing is 48/36/26 I use a 11/32 or 11/40 cassette. I occasionally use the 26t granny ring for above 10% mainly 36t for climbing and the 48t for flat fast pedalling. The gearing allows me to pedal at a decent cadence on all gradients and I can still ...

Re: Front and two rear lights from one dynamo?

You can happily run 3 led lights from a Shimano 3W hub. You can even charge a phone with a usb adaptor

Re: Anyone using an 11-speed 11-42t (or similar) with a triple chainset?

I was giving the example of range the gearing offers.

You are right, if I remember correctly, I hit 145rpm at 53mph coming down Mt Teide chasing down my pack. I would usually coast above 35mph, but I was having a bit of fun that day :D

Re: Anyone using an 11-speed 11-42t (or similar) with a triple chainset?

I have Kinesis Tripster ATR V2 which I have fitted a Deore Triple crankset 48/36/26 and I either use a 11-32 cass or 11-40 for mountains. This is shifted with XT/XTR Di2 front and rear on road shifters. I developed the setup from using a 44/28 mtb crankset. I use syncro shift to limit cross chaining...

Re: Cartridge bearing is rough when pressed in, but fine when taken out

The Watt saving using ceramic is extremely minimal. Ceramic are used for high speed applications, where dirt, water and grime are not really part of the equation. Adding the dust seal to the outside creates more drag than saved. Ceramic wear quickly once subjected to contaminants. Check out Hambini ...

Re: Getting started

You can buy a Tongscheng TSDZ2 custom kit from https://www.electrifybike.com/store/c24 ... ors.html#/ It can be programmed with custom firmware or come preset with it. They also sell high output Bafang systems

Both are crank drive

Re: Cartridge bearing is rough when pressed in, but fine when taken out

Check out Hambini on YouTube. He is an engineer, quite anal about tolerances of bike frames and bearings. He is quite outspoken about most aspects, but does talk sense. He manufactures his own Bottom bracket systems and helps clients with problems. He has slated quite a few high end frame makers and...

Re: If Rotor Uno can do it, why can't Shimano or SRAM!

Ive done it by blending two CS6800 cassettes. The easiest 5gears are fixed due to being rivetted together(2.3). But you can play with the other 6 to achieve what you want

Re: 50/34 chainsets and the older rider

I use different cadences and gearing for different events. I have a bike with gearing 115"-18" triple for mountains, I like to spin 90+ rpm. Using my TT bike I have a 56t chain ring to keep my cadence down 75rpm and develop as much power i can. I tend to do turbo training around 95-105 rpm...

Re: 105's - Getting More Granny Gearing

The chainset, you need to check whether its has a BCD 90mm. then you can use a 30t inner ring from the FSA adventurer range. Also fitting a 11 speed SRAM cass 11-36 with further enhance lower gearing. I used to have a twin setup 44/28 and upto 11-40 cass, but changed it to triple Di2 Deore 48/36/26 ...

Re: Conversion V Complete e bike in terms of range

I would look into a Bafang or Tongsheng TSDZ2 kits, go for the 48V motor/controller. You can get the kits with custom firmware to enhance range by being able to add 52V battery. £800 for a 400Wh battery, that is alot. I bought a 700Wh battery for £280 You just need a bike with a 68/73 threaded botto...
