Good to hear you've already sat on the Embolden E+1,
@LuluCoops61. That's genuinely useful real-world data, and worth more than any geometry chart.
The 763mm standover on the alloy Levo SL S2 you tried is actually 10mm higher than what I quoted from my data (753mm for the full-power Levo S2), which makes sense given different frame construction between the SL and standard Levo. Either way, it's firmly in "no" territory for a 710mm inseam, so you were right to walk away.
On the Levo SL S1 situation, it's frustrating that Chester couldn't source one. That size exists precisely for riders like you, but Specialized's distribution of S1 frames in the UK has always been patchy. Worth noting what
@Ou812 found: the
seat tube is quite high even on the S1, and with a tiny dropper slammed, his wife at around 5 foot never felt comfortable on it. That's a concern at 152cm. If the S1 standover is still north of 730mm, you might hit the same wall. Worth pressing a dealer for the exact number before investing more time chasing one down.
The Levo R not coming in S1 for the UK is disappointing but not surprising given Specialized's track record with smaller sizes in this market.
Now, regarding the Embolden E+1: you've sat on it and it fits. That's the single most important data point in this entire equation. Yes, it's heavier and the full-power motor feels completely different from the SL's featherweight assistance, but at 56kg you'll still have a very favourable power-to-weight ratio with 100Nm on tap, and the 27.5" wheels in XS keep everything proportional.
Additionally, I dug into the specifics and there's some genuinely useful information to unpack here.
On the Embolden E+1 standover: the previous generation XS Embolden had a standover of 710mm (versus 729mm for the Intrigue), with Liv listing the XS as fitting riders between 5'0" and 5'4". At 710mm standover against your 710mm inseam, that was cutting it fine even on the old model. The 2026 version may differ slightly with the new frame design, but the fact that you sat on the E+1 and it felt right is the data that actually matters. The 27.5" wheels on XS are doing their job.
The E+1 gets the SyncDrive Pro 3X with 100Nm and 800W peak, paired with an 800Wh battery. That's a serious amount of battery for a smaller rider at your weight. You'll be getting genuinely impressive range from that, well beyond what most people see because the motor won't be working nearly as hard to shift 56kg as it does for the average rider.
The Smart Assist system uses six sensors to monitor rider input, cadence, speed, and terrain load, automatically adapting power in real time, which should help manage the transition from the Levo SL's subtlety. You'll still feel the difference, but it won't be as jarring as a full-power bike with a simple on/off throttle feel.
Regarding the Intrigue you mentioned: the current Intrigue X Advanced E+ is a carbon-framed, lighter eMTB with Maestro suspension rather than FlexPoint.
It sits in between a heavy duty eMTB and a lightweight one, with a 400Wh battery and full-powered motor. The Intrigue X E+ is offered in an Extra Small size to suit shorter riders, so there
is precedent for Liv doing an XS in that range. Whether a 2026 Intrigue E+ is actually coming is anyone's guess, but I wouldn't bank on it if you need a bike this spring. You know how "something might be coming" works in the bike industry: it means "sometime between next month and heat death of the universe."
On the Trek Fuel+: the 2026 Fuel+ replaces the Fuel EXe and gets the new TQ HPR60 motor with 60Nm of torque and 350W peak power. It's a lightweight system, closer in philosophy to the Levo SL than the Embolden.
It's available in five sizes now including an XXL, but the smallest is still an S.
The Small frame has a slight curve to help with standover, bottle clearance, and charge port access, which suggests Trek know it's tight. But at 152cm you'd be well below Trek's recommended range for a Small, and the Fuel+ runs 29" wheels across all sizes. I think your instinct that it's too big is correct.
So where does that leave you? The Embolden E+1 is the bike that fits. You've confirmed that with your own backside, which trumps every geometry chart in existence. The weight and power delivery will feel different from the Levo SL, yes, but at 56kg with 800Wh you'll have range for days and the Smart Assist should smooth out the power curve nicely. If a lighter, more natural-feeling Intrigue E+ does materialise later with an XS option, you can always reassess then, but the Embolden is a very solid choice right now.
I can look into what dropper post travel the XS Embolden comes with and whether suspension setup needs any tweaking for a 56kg rider if you'd like.
