Hi,

I just ordered my 1st electric bike- a Ride1Up 700 series. Looks to be an awesome bike at a great deal, however, this requires more assembly than other brands. I'm pretty handy, but by no means a bike mechanic.

I understand that I will have to tighten things exactly to spec. Can someone help me select an affordable torque wrench or set (~$50 or less on Amazon) that can handle the following torque settings (4-39nm)?

Saddle Clamp Bolt: 16-17nm
Crank Arms: 39nm
Compression Cap (bolt): 4-5nm (make sure steering is still free but fork is not loose or wobbly.)
Stem/Steerer Clamp: 8-9nm
Handlebar Clamp: 8-9nm (tighten evenly in a cross pattern)

Thank you!

I have a ritchey torque key for 5nm bolts. Standard torque wrenches for the rest, but mostly the crank. I want a small torque wrench, for stuff in between, but most of it's not critical.

For me (obviously not everyone), the only thing I ever needed a torque wrench for was carbon parts, and now that I have carbon paste, that's not necessary. Just do it by feel, and haven't had a problem.

I'm not sure that I'd trust a torque wrench that cost less than $50. Perhaps you can find one of the flexible beam types - these are certainly not high-tech (and they don't need periodic recalibration)

Because of the wide range of torques you may need more than one wrench.

I think I would only need a 5nm wrench. The bigger bolts I can do by feel. The bike specific tools look very handy. This one has been tested a a bike group and rated accurate.

I've had a Tekton 1/4" drive torque wrench for about a year now. Seems to work great.

Highly recommend the BBB Cycling BTL-73. Packed in useful compact case with most common hex bit sizes. Accurate, fine adjustment.
BTW, that spec above for 'saddle clamp bolt' sounds rather high.
If new to torque wrenches, strongly suggest you get a couple of metric nuts/bolts from home depot, drill out a piece of wood, then practice getting the feel of the process before you operate on your loved one. With most wrenches, it's something you should 'get a feel for' with just a little practice. Most dial-in wrenches are not really a "click" but more of a "cam slip" and it's good to really experiment a bit before you're tightening on carbon.

I don't think you really need anything fancy. I have a couple of those lever arm ones that come with Canyon bikes that I use if I'm worried.

Generally though its the low torque stuff that I am concerned about. Too much torque on those and stuff breaks. I like to do it by hand, but the gentle stuff needs something I can measure.

if its not 5nm, I just do it by hand:

Why buy a piece of junk from Jeff Bezos that 1) you’re only going to use once 2) you can’t even trust that it’s accurate?

Just rent one for like $20 from Autozone/Advance Auto/NAPA that is not a piece of junk.

So does Autozone or whoever guarantee the accuracy of rental torque wrenches? And pay for damage to your bike if the wrench reads low? I don't trust renting things like tools - don't know what abuse the last renter might have subjected it to.
