It's a Mongoose envoy cargo bike


I want to raise the stem higher so I don't have to Bend forward to hold the bars.

I've used this type of thing maybe not this brand. double check the diameter size

Delta Cycle Bike Bicycle Stem Raiser Extender Head Up Handlebar Raiser

Get a stem with more rise, or a handlebar with more rise. Or both.

I agree that the handlebars in the picture are too low. Try putting the stem with the bars on the steerer tube. <grin>

what size is the bike? how tall are you? it the bike sized correclty

Per Mongoose: the Envoy come in S/M & M/L. Suggested rider height of S/M is 5’5” to 5’10” (floor to Top tube of 30. 5"-33"), and 5’10” to up (floor to Top tube of 33") for the M/L.

It's the S/M and I'm about 5'9.

I don't know how to get the old stem out.

I want to get a longer stem with an extender so I can move it up and forward.

A high rise stem can increase the handlebar height by an inch or 2:

As Rolla and tyrion said, you need to get a stem that is angled upward and/or some new bars that have a rise to them.... riser bars.


The thing coming out of the head tube of your bike is the steerer tube that is attached to the fork. They do make extenders for the steerer tube, but I wouldn't recommend them unless you are a very gentle rider and never yank on the bars as you power up a hill.

Not that I know they are problematic from any experience. Just that they don't seem right to me. Besides, you really need a bike that has a stack height that puts the bars where you want them without all the extra stuff. Aesthetically weirdly angled stems and bars way higher than the head tube just look atrocious to me.

But I'm okay if you don't care to satisfy my sense of aesthetics. I don't chuckle loud enough for any to hear me when they pass. <grin>

My guess is that at 5'9, you're one size too small - probably should be on a medium at least, not small/medium. That said, you should be able to safely bring up your bars with the angled stem mentioned above or a steer tube extender like the two pictured below. With a metal steer tube, I think they should be well within spec, but you might want to check to make sure. I wouldn't use one on a carbon fiber steer tube though.

I do have 1st hand experience with stem risers. used one on a commuter I tortured for years. it never budged. got one now on my road bike, same thing, works great, solid, fast & easy to install. but it doesn't provide the forward adjustment the OP mentioned

If you need higher and more forward (more reach), get a steering tube extender as others have mentioned. High angle, high rise stems have limited reaches.

I know what you mean. I feel the same way (they don't seem right), however...I do have one on a Surly Pugsley fat bike with a wide handlebar with bar ends and I do stand up and crank on it and wrench on the bar ends and that stem extender hasn't let go yet. Installed properly, they do seem to work...dodgy though they may seem...

In the photos, your stem has already been removed. I think what you are calling a stem is actually the steerer tube. You will not be able to replace the steering tube without replacing the entire fork (that's an option, btw).


Also, you might be able to avoid the whole steering tube extender thing by buying a handlebar that has more rise. This, in addition to a more angled stem, can raise the front end by several inches if you want that.



If you want a Jones-style bar like in your photo, Jones makes one with 2.5" of rise:

Thanks for all the help I appreciate all the responses.

If I understand this correctly the tube coming out of my fork can not be removed or raised. My options are to extend the tube and replace the stem with one that is longer and has more angle?

Another thing is that I don't like this style of handlebar. I prefer the curved ones like I had on my city bike. I should probably find one of those first and then see about changing the stem?

Correct.

Correct. And/or replace the handlebar with one that has rise.

Not sure what you mean by "curved," but if they are road-bike style handlebars, your current shifters and brake levers won't fit on them. Also, whether you change the stem or the handlebar or both, the handlebar clamping area should be the same diameter as the stem clamp diameter (although you can shim it if the bar is narrower than the stem clamp).

Yes. Get the bars that your hands like then get the stem (and steerer extension if needed) that puts those bars where you want them
